Moon Mountain Named After Melba Roy Mouton, NASA Mathematician

View these celestial beauties taken by the Hubble Space Telescope and released as a set of views in a modern day "Messier Catalog." 

Spotting comets was all the rage in the middle of the 18th century, and at the forefront of the comet hunt was a young French astronomer named Charles Messier. In 1774, in an effort to help fellow comet seekers steer clear of astronomical objects that were not comets (something that frustrated his own search for these elusive entities), Messier published the first version of his “Catalog of Nebulae and Star Clusters,” a collection of celestial objects that weren’t comets and should be avoided during comet hunting. Today, rather than avoiding these objects, many amateur astronomers actively seek them out as interesting targets to observe with backyard telescopes, binoculars or sometimes even with the naked eye.

Hubble’s version of the Messier catalog includes eight newly processed images never before released by NASA. The images were extracted from more than 1.3 million observations that now reside in the Hubble data archive. Some of these images represent the first Hubble views of the objects, while others include newer, higher resolution images taken with Hubble’s latest cameras.

The Hunt for New Worlds Continues with TESS

We're getting ready to start our next mission to find new worlds! The Transiting Exoplanet Survey Satellite (TESS) will find thousands of planets beyond our solar system for us to study in more detail. It's preparing to launch from our Kennedy Space Center at Cape Canaveral in Florida.

Once it launches, TESS will look for new planets that orbit bright stars relatively close to Earth. We're expecting to find giant planets, like Jupiter, but we're also predicting we'll find Earth-sized planets. Most of those planets will be within 300 light-years of Earth, which will make follow-up studies easier for other observatories.

TESS will find these new exoplanets by looking for their transits. A transit is a temporary dip in a star's brightness that happens with predictable timing when a planet crosses between us and the star. The information we get from transits can tell us about the size of the planet relative to the size of its star. We've found nearly 3,000 planets using the transit method, many with our Kepler space telescope. That's over 75% of all the exoplanets we've found so far!

TESS will look at nearly the entire sky (about 85%) over two years. The mission divides the sky into 26 sectors. TESS will look at 13 of them in the southern sky during its first year before scanning the northern sky the year after.

What makes TESS different from the other planet-hunting missions that have come before it? The Kepler mission (yellow) looked continually at one small patch of sky, spotting dim stars and their planets that are between 300 and 3,000 light-years away. TESS (blue) will look at almost the whole sky in sections, finding bright stars and their planets that are between 30 and 300 light-years away.

TESS will also have a brand new kind of orbit (visualized below). Once it reaches its final trajectory, TESS will finish one pass around Earth every 13.7 days (blue), which is half the time it takes for the Moon (gray) to orbit. This position maximizes the amount of time TESS can stare at each sector, and the satellite will transmit its data back to us each time its orbit takes it closest to Earth (orange).

Kepler's goal was to figure out how common Earth-size planets might be. TESS's mission is to find exoplanets around bright, nearby stars so future missions, like our James Webb Space Telescope, and ground-based observatories can learn what they're made of and potentially even study their atmospheres. TESS will provide a catalog of thousands of new subjects for us to learn about and explore.

The TESS mission is led by MIT and came together with the help of many different partners. Learn more about TESS and how it will further our knowledge of exoplanets, or check out some more awesome images and videos of the spacecraft. And stay tuned for more exciting TESS news as the spacecraft launches!

What’s Up for October?

This month is filled with exciting celestial sights. Here are 10 targets you can view this month:

10. Unusual Sunset

During a sunset, our thick atmosphere absorbs most colors of sunlight, but red light is absorbed the least. Rarely, green flashes can be seen just above the sun’s edge. As the last sliver of the disk disappears below the horizon, be sure to watch its color.

9. Belt of Venus

Just after sunset, turn around and face east. A dark shadow will move up from the horizon and gradually cover the pinkish sky. This is caused from the Earth itself blocking the sunlight and is called the Earth Shadow or the Belt of Venus.

8. Crepuscular Rays

Also just after sunset, or before dawn, you may see rays of sunlight spread like a fan. These are called crepuscular rays and are formed when sunlight streams through gaps in the clouds or mountains.

7. Aurora Borealis

The northern lights, also known as the aurora borealis, are caused by collisions between gaseous particles in Earth’s atmosphere and charged particles released from the sun. The color of the lights can changed depending on the type of gas being struck by particles of solar wind. You can find out when and where to expect aurorae at the Space Weather Prediction Center.

6. Andromeda Galaxy

Did you now that The Andromeda Galaxy is one of the few you can actually see with your naked eye? In October, look nearly overhead after sunset to see it! This galaxy is more than twice the apparent width of the moon.

5. Moon Features

Nights in mid-October are excellent for viewing the features on the moon. Areas like the Sea of Tranquility and the site of the 1969 Apollo 11 landing will be visible.

4. A Comet

This month, the European Space Agency’s Rosetta mission target, a comet with a complicated name (Comet 67P Churyumov-Gerasimenko), is still bright enough for experienced astronomers to pick out in a dark sky. On October 9, you may be able to spot it in the east near the crescent moon and Venus.

3. Meteor Showers

There are multiple meteor showers this month. On the 9th: watch the faint, slow-moving Draconids. On the 10th: catch the slow, super-bright Taurids. And on the 21st: don’t’ miss the swift and bright Orionids from the dust of Comet Halley.

2. Three Close Planets

On October 28, you’ll find a tight grouping of Jupiter, Venus and Mars in the eastern sky before sunrise.

1. Zodiacal Light

The Zodiacal light is a faint triangular glow that can be seen from a dark sky after sunset or before sunrise. What you’re seeing is sunlight reflecting off dust grains that circle the sun in the inner solar system. These dust grains travel in the same plane as the moon and planets as they journey across our sky.

What Makes the Artemis Moon Mission NASA's Next Leap Forward?

When NASA astronauts return to the Moon through Artemis, they will benefit from decades of innovation, research, and technological advancements. We’ll establish long-term lunar science and exploration capabilities at the Moon and inspire a new generation of explorers—the Artemis Generation.

Meet the Space Launch System rocket, or SLS. This next-generation super heavy-lift rocket was designed to send astronauts and their cargo farther into deep space than any rocket we’ve ever built. During liftoff, SLS will produce 8.8 million pounds (4 million kg) of maximum thrust, 15 percent more than the Saturn V rocket.

SLS will launch the Orion spacecraft into deep space. Orion is the only spacecraft capable of human deep space flight and high-speed return to Earth from the vicinity of the Moon. More than just a crew module, Orion has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module, which is the powerhouse that fuels and propels Orion and keeps astronauts alive with water, oxygen, power, and temperature control.

Orion and SLS will launch from NASA’s Kennedy Space Center in Florida with help from Exploration Ground Systems (EGS) teams. EGS operates the systems and facilities necessary to process and launch rockets and spacecraft during assembly, transport, launch, and recovery.

The knowledge we've gained while operating the International Space Station has opened new opportunities for long-term exploration of the Moon's surface. Gateway, a vital component of our Artemis plans, is a Moon-orbiting space station that will serve as a staging post for human expeditions to the lunar surface. Crewed and uncrewed landers that dock to Gateway will be able to transport crew, cargo, and scientific equipment to the surface.

Our astronauts will need a place to live and work on the lunar surface. Artemis Base Camp, our first-ever lunar science base, will include a habitat that can house multiple astronauts and a camper van-style vehicle to support long-distance missions across the Moon’s surface. Apollo astronauts could only stay on the lunar surface for a short while. But as the Artemis base camp evolves, the goal is to allow crew to stay at the lunar surface for up to two months at a time.

The Apollo Program gave humanity its first experience traveling to a foreign world. Now, America and the world are ready for the next era of space exploration. NASA plans to send the first woman and first person of color to the lunar surface and inspire the next generation of explorers.

Our next adventure starts when SLS and Orion roar off the launch pad with Artemis I. Together with commercial and international partners, NASA will establish a long-term presence on the Moon to prepare for missions to Mars. Everything we’ve learned, and everything we will discover, will prepare us to take the next giant leap: sending the first astronauts to Mars.

uhmm, can you tell me what exactly a black hole is? or what iy does? thanks, just really confused and curious on how it actually works.

Exploring Hell... up for the challenge?

Venus is an EXTREME world, and we’re calling on YOU to help us explore it! NASA Jet Propulsion Laboratory is running a public challenge to develop an obstacle avoidance sensor for a possible future Venus rover. 

With a surface temperature in excess of 840 degrees Fahrenheit and a surface pressure 92 times that of Earth, Venus can turn lead into a puddle and crush a nuclear-powered submarine with ease. While many missions have visited our sister planet, only about a dozen have made contact with the surface of Venus before succumbing to the oppressive heat and pressure after just about more than an hour.

The “Exploring Hell: Avoiding Obstacles on a Clockwork Rover” challenge is seeking the public’s designs for a sensor that could be incorporated into the design concept. The winning sensor could be the primary mechanism by which the rover detects and navigates around obstructions.

Award: 1st Place - $15,000; 2nd Place - $10,000; 3rd Place - $5,000

Open Date: February 18, 2020  ––––––––– Close Date: May 29, 2020

Ten Observations From Our Flying Telescope

SOFIA is a Boeing 747SP aircraft with a 100-inch telescope used to study the solar system and beyond by observing infrared light that can’t reach Earth’s surface.

What is infrared light? It’s light we cannot see with our eyes that is just beyond the red portion of visible light we see in a rainbow. It can be used to change your TV channels, which is how remote controls work, and it can tell us how hot things are.

Everything emits infrared radiation, even really cold objects like ice and newly forming stars! We use infrared light to study the life cycle of stars, the area around black holes, and to analyze the chemical fingerprints of complex molecules in space and in the atmospheres of other planets – including Pluto and Mars.

Above, is the highest-resolution image of the ring of dust and clouds around the back hole at the center of our Milky Way Galaxy. The bright Y-shaped feature is believed to be material falling from the ring into the black hole – which is located where the arms of the Y intersect.

The magnetic field in the galaxy M82 (pictured above) aligns with the dramatic flow of material driven by a burst of star formation. This is helping us learn how star formation shapes magnetic fields of an entire galaxy.

A nearby planetary system around the star Epsilon Eridani, the location of the fictional Babylon 5 space station, is similar to our own: it’s the closest known planetary system around a star like our sun and it also has an asteroid belt adjacent to the orbit of its largest, Jupiter-sized planet.

Observations of a supernova that exploded 10,000 years ago, that revealed it contains enough dust to make 7,000 Earth-sized planets!

Measurements of Pluto’s upper atmosphere, made just two weeks before our New Horizons spacecraft’s Pluto flyby. Combining these observations with those from the spacecraft are helping us understand the dwarf planet’s atmosphere.

A gluttonous star that has eaten the equivalent of 18 Jupiters in the last 80 years, which may change the theory of how stars and planets form.

Molecules like those in your burnt breakfast toast may offer clues to the building blocks of life. Scientists hypothesize that the growth of complex organic molecules like these is one of the steps leading to the emergence of life.

This map of carbon molecules in Orion’s Horsehead nebula (overlaid on an image of the nebula from the Palomar Sky Survey) is helping us understand how the earliest generations of stars formed. Our instruments on SOFIA use 14 detectors simultaneously, letting us make this map faster than ever before!

Pinpointing the location of water vapor in a newly forming star with groundbreaking precision. This is expanding our understanding of the distribution of water in the universe and its eventual incorporation into planets. The water vapor data from SOFIA is shown above laid over an image from the Gemini Observatory.

We captured the chemical fingerprints that revealed celestial clouds collapsing to form young stars like our sun. It’s very rare to directly observe this collapse in motion because it happens so quickly. One of the places where the collapse was observed is shown in this image from The Two Micron All Sky Survey.

Hurricanes Have No Place to Hide, Thanks to Better Satellite Forecasts

If you’ve ever looked at a hurricane forecast, you’re probably familiar with “cones of uncertainty,” the funnel-shaped maps showing a hurricane’s predicted path. Thirty years ago, a hurricane forecast five days before it made landfall might have a cone of uncertainty covering most of the East Coast. The result? A great deal of uncertainty about who should evacuate, where it was safe to go, and where to station emergency responders and their equipment.

Over the years, hurricane forecasters have succeeded in shrinking the cone of uncertainty for hurricane tracks, with the help of data from satellites. Polar-orbiting satellites, which fly nearly directly above the North and South Poles, are especially important in helping cut down on forecast error.

The orbiting electronic eyeballs key to these improvements: the Joint Polar Satellite System (JPSS) fleet. A collaborative effort between NOAA and NASA, the satellites circle Earth, taking crucial measurements that inform the global, regional and specialized forecast models that have been so critical to hurricane track forecasts.

The forecast successes keep rolling in. From Hurricanes Harvey, Irma and Maria in 2017 through Hurricanes Florence and Michael in 2018, improved forecasts helped manage coastlines, which translated into countless lives and property saved. In September 2018, with the help of this data, forecasters knew a week ahead of time where and when Hurricane Florence would hit. Early warnings were precise enough that emergency planners could order evacuations in time — with minimal road clogging.  The evacuations that did not have to take place, where residents remained safe from the hurricane’s fury, were equally valuable.

The satellite benefits come even after the storms make landfall. Using satellite data, scientists and forecasters monitor flooding and even power outages. Satellite imagery helped track power outages in Puerto Rico after Hurricane Maria and in the Key West area after Hurricane Irma, which gave relief workers information about where the power grid was restored – and which regions still lacked electricity. 

Flood maps showed the huge extent of flooding from Hurricane Harvey and were used for weeks after the storm to monitor changes and speed up recovery decisions and the deployment of aid and relief teams.

As the 2019 Atlantic hurricane season kicks off, the JPSS satellites, NOAA-20 and Suomi-NPP, are ready to track hurricanes and tropical cyclones as they form, intensify and travel across the ocean – our eyes in the sky for severe storms.
