  1. 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🧛🏽‍♀️

    A white dwarf is seen as a bright light surrounded by a flat accretion disk of material, stripping away more material from a smaller, darker brown dwarf.
  2. Our Spitzer Space Telescope just ended a successful 16+ year mission. It was one of 's Great Observatories along with , & Compton. You could even call them ... super😉 See how they changed our view of the cosmos⬇️

  3. "Mission manager, loss of signal has been confirmed." Friends & family of the Spitzer mission gathered at yesterday as the spacecraft performed its final command. See the scene from mission control – and why it was so important.

  4. Many of Spitzer's breakthroughs will be further studied by . 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.

  5. . was one of NASA's Great Observatories – with , & 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.

  6. "I think that Spitzer is an example of the very best that people can achieve." – Project Scientist Michael Werner

  7. "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." – , associate administrator

  8. "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, project manager, calling end of mission.

  9. Engineers confirm '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🖤

  10. Happening now: 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.

  11. Space exploration is a profoundly human endeavor. On 's Day of Remembrance, we honor those who lost their lives while furthering exploration and discovery, and look to the stars in their honor.

    Stars and jets are seen against the black of space as bright blue, white and green dots amid a red haze.
  12. To celebrate , why not picture yourself in some of its most amazing images? We've added new images to our app for iOS/Android. Take a selfie🤳🏾 and see yourself in parts of the universe Spitzer explored.

  13. Yesterday, 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.

  14. Today is '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.

  15. 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.

    Good question! Check out this infographic for more about that⬇️

  17. In the , 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.

    Plate tectonics and volcanism could also influence an exoplanet's habitability.
