#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://go.nasa.gov/3aZ94yV pic.twitter.com/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.#SpitzerFinalVoyagepic.twitter.com/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://www.nasa.gov/feature/goddard/2020/cosmic-magnifying-glasses-yield-independent-measure-of-universes-expansion …pic.twitter.com/8UznUUvjm7Hvala.

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.

#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://go.nasa.gov/2sXFpVI pic.twitter.com/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://go.nasa.gov/38ogkCn pic.twitter.com/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://go.nasa.gov/388GGYW pic.twitter.com/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.pic.twitter.com/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://go.nasa.gov/39RCsGM pic.twitter.com/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://go.nasa.gov/2N5Kz8O pic.twitter.com/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://go.nasa.gov/303f8kJ pic.twitter.com/dRz11LGPcf

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://go.nasa.gov/2QrATYh pic.twitter.com/CmDHsFoTVK

This majestic spiral galaxy might earn the nickname the "Godzilla galaxy" because it may be the largest known in the local universe. The galaxy, UGC 2885, is 2.5 times wider than our Milky Way and contains 10 times as many stars: https://go.nasa.gov/2MZxjCy pic.twitter.com/7q8LzYIUgs

#HubbleFriday Spiral galaxy NGC4455 is located in the constellation Coma Berenices. This may sound like an odd name and in fact it is somewhat unusual.

#HubbleClassic Just weeks after astronauts finished working on Hubble in Dec. 1999, the telescope captured this shot of NGC 1999, a nebula lit by the star V380 Orionis. Infrared observations show that the dark region near the star is a hole in the nebula: https://go.nasa.gov/2ML5j5C pic.twitter.com/99hMwYGuQ3
