Researchers made a rare find in data from our retired Kepler spacecraft: a super-outburst
from a previously unknown dwarf nova. The star system consists of a white dwarf that's stripping material from a much smaller brown dwarf, like a stellar vampire

Our Spitzer Space Telescope just ended a successful 16+ year mission. It was one of
@NASA's Great Observatories along with@NASAHubble,@chandraxray & Compton. You could even call them ... super
See how they changed our view of the cosmos

"Mission manager, loss of signal has been confirmed." Friends & family of the Spitzer mission gathered at
@NASAJPL yesterday as the spacecraft performed its final command. See the scene from mission control – and why it was so important. https://go.nasa.gov/2GDTQS2 pic.twitter.com/C8MtuiKRob -
Many of Spitzer's breakthroughs will be further studied by
@NASAWebb. Webb is also specialized for infrared, but is about 1,000 times more powerful. The telescope will be able to push Spitzer's science findings to new frontiers. https://go.nasa.gov/2uR5FkX pic.twitter.com/WqaXom2e8ePrikaži ovu nit -

@NASAspitzer was one of NASA's Great Observatories – with@NASAHubble,@chandraxray & Compton – designed to observe the cosmos in different wavelengths. Spitzer specialized in infrared, peering beyond visible light. Think of them as our space telescope superteam.pic.twitter.com/7fRqTT1XR3Spitzer and NASA’s ‘Great Observatories’ Space TelescopesThis is the animated tale of the Spitzer spacecraft and the space telescope superteam known as NASA’s Great Observatories, which also includes Hubble, Chandra and Compton.Prikaži ovu nit -
"I think that Spitzer is an example of the very best that people can achieve." –

"Spitzer has taught us about entirely new aspects of the cosmos and taken us many steps further in understanding how the universe works, addressing questions about our origins, and whether or not are we alone." –

"There are literally hundreds of people who contributed directly to Spitzer's success, and thousands who used its scientific capabilities to explore the universe. We leave behind a powerful legacy." – Joseph Hunt,

Engineers confirm
@NASAspitzer's mission ended today. The spacecraft is in safe mode, as planned. In 16+ years in space, Spitzer changed our understanding of the universe & was a pathfinder for space telescopes to come. It was a very good spacecraft

Happening now:
@NASAspitzer will soon be receiving its final commands to decommission the spacecraft. It has served for more than 16 years, unveiling our universe in wavelengths beyond what our eyes can see. It opened worlds to us.#SpitzerFinalVoyagepic.twitter.com/dZABUD9x7i -
Space exploration is a profoundly human endeavor. On
@NASA's Day of Remembrance, we honor those who lost their lives while furthering exploration and discovery, and look to the stars in their honor.#NASARemembers https://go.nasa.gov/36G04eC pic.twitter.com/K9sjTHjNGa

To celebrate
#SpitzerFinalVoyage, why not picture yourself in some of its most amazing images? We've added new images to our#NASAselfies app for iOS/Android. Take a selfie
and see yourself in parts of the universe Spitzer explored. https://go.nasa.gov/2ASnNvi pic.twitter.com/tFlMWk7boo -
Yesterday,
@NASAspitzer was sending and receiving some of the last data for the space telescope. After 16+ years in space, Spitzer's mission will end tomorrow. We're thankful for the science and that the spacecraft was able to serve for so long.#SpitzerFinalVoyagepic.twitter.com/zMtbdHnu5u -
Today is
@NASAspitzer's
6,000th day of science. After 16+ years in space, our explorer's mission will end Jan. 30.
Just as discoveries are still being made from Kepler's
data, Spitzer's legacy will continue with its data archive. #SpitzerFinalVoyage https://go.nasa.gov/38JWqlf pic.twitter.com/MTL8npaO3Y -
KELT-9b is the hottest exoplanet, a planet beyond our own solar system, that we know of. It has a surface temperature
of 7,800℉ (4,300℃), hotter than some stars
The heat
likely rips molecules in its atmosphere to shreds.

In the
#SearchForLife, a planet’s surface features are also important. Volcanoes
, for instance, could bring important elements like CO2, nitrogen and water, needed for life (as we know it) to a planet’s surface.pic.twitter.com/Mblx36nEYH

Conditions for liquid surface water
help determine a planet’s habitability in our #SearchForLife, but icy worlds
are intriguing, too!pic.twitter.com/3jwTNQG3a7

Atmospheres are also important in our
#SearchForLife. Detecting gases made by life (as we know it so far) is one way to help confirm a planet’s habitability.pic.twitter.com/yoSJknJNz0

When we
#SearchForLife, an area of focus is the “Goldilocks zone,”


where conditions are “just right” for liquid water
to exist on a planet’s surface


But, that’s just ONE thing we think about!pic.twitter.com/EtJM4jX1C1
