#HubbleClassic The Ant Nebula (also known as Menzel 3) resembles the head and thorax of a garden-variety ant. It's produced by a dying Sun-like star as it sheds its outer layers of gas. For more information: https://t.co/tZf7hZvvfF https://t.co/yZPcXYjbs0

#HubbleFriday NGC 2008 is located ~425 million light-years from Earth. Discovered in 1834 by astronomer John Herschel, this galaxy is categorized as a type Sc galaxy in the Hubble sequence, a system used to classify the various morphologies of galaxies: https://t.co/sxUqv4MkXJ https://t.co/Ex1R8oAj5i

Thank you for all of the support @NASASCaN  Happy Valentine's Day! https://t.co/o2QGO34Vgq

As the Hubble Space Telescope celebrates its 30th year in operation, the team behind Hubble will receive the 2020 Collins Trophy for Current Achievement from the @airandspace museum. Read more about this prestigious award: https://t.co/Q6t8GTdWDT https://t.co/wEE2gZC0Wx

#HubbleClassic Dark clouds of dust & gas float in front of a bright nebula where new stars are forming. First found by astronomer A.D. Thackeray in 1950, they're known as Thackeray's Globules: https://t.co/mIW5AbzuLc https://t.co/2VeNIrTvQc

#HubbleFriday Unmistakably a spiral, NGC 5364 is also something known as a grand design spiral galaxy — a descriptive name deserved by only one-tenth of spirals: https://t.co/HMlD7mLHtz https://t.co/MU1Kwb2G1w

#HubbleClassic In February 1995, Hubble captured this image of a bow shock near the star LL Orionis in the Orion Nebula. It's formed as a strong "wind" of particles from the star collides with slow-moving gas in the nebula. For more information: https://t.co/FIdfZBEQqN https://t.co/Fs7hk2kG87

#HubbleFriday Barred spiral galaxy NGC7541 appears to have a higher-than-usual star formation rate, adding weight to the theory that spiral bars act as stellar nurseries, funneling inward the material and fuel needed to create new baby stars: https://t.co/8CszP4iuD0 https://t.co/pdKXpf2klw

#HubbleClassic For 16 years, Hubble has worked with @NASASpitzer to study the universe at different wavelengths of light, providing unique views like these of galaxy M81. Farewell, friend. It's been wonderful exploring with you. #SpitzerFinalVoyage https://t.co/Z1iDtQbtAD

Today is #NationalPuzzleDay! 🧩 One of the major puzzles in astrophysics is the expansion rate of the universe, also known as the Hubble constant. Completely understanding the universe’s expansion might require new laws of physics: https://t.co/qg8Q0dcmCd https://t.co/8UznUUvjm7

Hubble welcomes the Year of the Rat with a view of its own favorite rodents, NGC 4676A and B, and highlights the planetary origins of the Chinese zodiac’s 12-year timetable. #LunarNewYear https://t.co/wrUpDfB4ZE

#HubbleFriday Hubble observed NGC1022 as part of a study into one of the universe’s most notorious residents: black holes. These are fundamental components of galaxies and are thought to lurk at the hearts of many — if not all — spirals: https://t.co/ac8bEOd41D https://t.co/msz6sdfphi

#HubbleClassic Hubble took >7,000 exposures to create this mosaic of a 48,000-light-year span across the Andromeda Galaxy, our largest galactic neighbor. The image is so detailed it resolves individual stars in the galaxy from 2 million light-years away: https://t.co/NB1jt7UcKW https://t.co/gcp23BIL8q

#HubbleFriday This bright, somewhat blob-like object is a galaxy named NGC 1803. It is about 200 million light-years away, in the southern constellation of Pictor. NGC 1803 was discovered in 1834 by astronomer John Herschel. For more information: https://t.co/Aho93cQmn6 https://t.co/PAI6E7PWb4

#HubbleClassic #OTD in 1994, Hubble released this image of the massive star system Eta Carinae and the billowing clouds of gas & dust around it. The picture was taken by the Wide Field and Planetary Camera 2, installed just a month earlier. https://t.co/oqGpeHUC2v

#AAS235 An emerging idea, bolstered by surveys from Hubble and other telescopes, is that orange dwarfs are "Goldilocks stars" — not too hot, not too cool, and above all, not too violent to host life-friendly planets over a vast horizon of cosmic time: https://t.co/K4DoBwWHw1 https://t.co/PwH0qQtT7i

#AAS235 Calculating the expansion rate of the universe is a mystery that has been one of the greatest challenges in astrophysics in recent years. A new study adds evidence to the idea that new theories may be needed to explain what scientists are finding: https://t.co/BuI6sN3yoa https://t.co/ZouJGnJo04

#AAS235 Astronomers have detected dark matter clumps around large- and medium-sized galaxies. Now, using Hubble and a new observing technique, astronomers have found that dark matter forms much smaller clumps than previously known: https://t.co/kaLWfXaEDQ https://t.co/dRz11LGPcf

Stay tuned this hour for 3 special Hubble news stories from #AAS235!

This is the farthest galaxy group identified to date. Three galaxies of the EGS77 galaxy group, shown in the green circles, lie at a redshift of 7.7, which means we’re seeing them as they were when the universe was just 680 million years old: https://t.co/inao1cURGZ https://t.co/CmDHsFoTVK
