This #Hubble image showcases the spiral galaxy NGC 1309, located 100 million light-years from Earth. It is notable for being home to both Cepheid variable stars and a Type Ia supernova, helping astronomers calibrate the cosmic distance ladder: https://bit.ly/47yVtdK
Continuing our 19 days of #PHANGS galaxies, we have the barred spiral galaxy NCG 1385, as seen by #Hubble and #JWST.
NCG 1385 is notable for its asymmetry — it has a bar structure surrounding its core, but its spiral arms are all on the left side of the image. It is known as a flocculent spiral, a galaxy with a large number of chaotic fragmented arms.
The galaxy is about 56 million light years (17 Mpc) away.
Next in our 19 days of #PHANGS galaxies is another gorgeous barred spiral galaxy, NCG 1365, as seen by #Hubble and #JWST.
These images are zoomed-in — they only cover the galaxy’s center, giving us a good view of the "spiral within a spiral" common in galaxies with large bars. We see a hint of the spiral arms at the edges.
Next in our 19 days of #PHANGS galaxies is perhaps the prototypical face-on barred spiral galaxy, NCG 1300, as seen by #Hubble and #JWST.
Instead of starting at the galaxy’s core, the arms of barred spirals like NCG 1300 begin at the end of a large bar-shaped structure, filled with older stars.
Two prominent dust lanes cut through the bar, ending in a spiral feature at the center — a spiral within a spiral.
Our next galaxy in the 19 days of #PHANGS series is NGC 1087, a face-on spiral with a rather odd short bar at its center, as seen by #Hubble and #JWST.
Most barred spiral galaxies have a large, linear bar structure at their centers, filled with older stars. However, NGC 1087 may show signs of new star formation in its center, which is somewhat puzzling.
The galaxy is about 50 million light years (15.9 Mpc) away.
Featured in Nature's selection of the best #science images of the month: a composite image of the Cassiopeia A #supernova remnant that brings together data from several #NASA telescopes: X-rays from #Chandra, infrared from #JWST & #Spitzer, optical data from #Hubble.
Next in our 19 days of #PHANGS galaxies is the face-on spiral IC 5332, as seen by #Hubble and #JWST.
It is located about 30 million light-years (8.84 Mpc) away.
The name comes from the 1910 Second Index Catalogue of Nebulæ and Clusters of Stars (IC). This was from a time before astronomers distinguished between nebulas and galaxies. It was discovered by Lewis Swift in 1896 at the Lowe Observatory in California, who noted it was extremely faint.
Una amabile chiacchierata con Alberto Negri (SpazioTesla) su tre grandi telescopi in orbita, e su come stanno cambiano la nostra stessa consapevolezza di osservatori del cosmo... #hubble#jwst#euclid
First up in our 19 days of #PHANGS galaxies is NGC 628, as seen by #Hubble and #JWST.
Also known as M74 or the "Phantom Galaxy," it is a face-on spiral galaxy about 32 million light-years (9.84 Mpc) away. It’s known as a “grand design spiral,” because its spiral arms are very prominent and well-defined.
The galaxy was discovered in 1780 by Pierre Méchain, and entered as object 74 in Charles Messier’s catalog of fuzzy things in the night sky that were not comets.
Today @spacetelescope released 19 images of face-on spiral galaxies from #JWST and #Hubble. The new JWST images were taken as part of the PHANGS program, a survey of nearby galaxies taking high-resolution observations with ALMA, the VLT, Hubble and JWST.
This is now a #PHANGS galaxy stan account. Over the next 19 days, I’ll post a short thread about each one of the galaxies featured in today’s release.

@spacetelescope And by popular request, high-res versions of the split-view #Hubble and #JWST images of #PHANGS galaxies are now available to download.
Stasera lunedì 29 gennaio, ore 19.00, sono in diretta #Youtube con Alberto Negri di Spazio Tesla per una chiacchierata su tre grandi telescopi del recente passato e della contemporaneità: parleremo di Hubble Space Telescope, del NASA's James Webb Space Telescope e di Euclid. #hubble#jwst#euclid
I particolari per collegarsi, al link qui di seguito.
Sarà possibile porre domande tramite i commenti YouTube.
Vi aspetto!
GJ 9827d, an exoplanet just spotted by Hubble, is no larger than twice the size of Earth and may possess a water-rich atmosphere - but temperatures there go over 800°F, similar to Venus. So, an incredibly steamy place. (The discovery is remarkable because GJ 9827d is currently the smallest exoplanet where such a discovery has been made.)
Astronomers using #Hubble have found evidence of water vapor on the exoplanet GJ 9827d, which is 97 light-years away. No bigger than twice Earth’s diameter, the planet could be an example of water-rich worlds elsewhere in our galaxy: bit.ly/429Ja6x
Behold! A sea creature in the deep, dark depths of … space?
Meet the Stingray nebula, located 18,000 light-years from Earth. Though stingrays in Earth’s oceans have periods of inactivity, #Hubble revealed that this nebula is active: https://bit.ly/3RqVfzc
The Hubble captured a detailed image of an amazing looking part of IC 438, a spiral galaxy located 130 million light-years away in the constellation of Lepus
Neat "zoom-in" on the Horsehead Nebula in the #constellation#Orion (check out our latest #podcast episode for more on the #astronomy of this constellation!)
Not really. The Voyager 2 images of Neptune were both contrast enhanced and colored a little too blue, differing from true color to bring out the details of the planet. Sorry to ruin your childhood.
Here is a re-colored version of the Voyager 2 images, using additional color data from #Hubble and #ESO's Very Large Telescope to get closer to the "true color".
