We are joining Carnegie Science in celebrating the 100th anniversary of Edwin Hubble’s discovery of galaxies existing beyond our Milky Way. He found a stellar “milepost marker” embedded in Andromeda and calculated it is outside our galaxy: https://bit.ly/40r30L6 #AAS245

#NASAWebb has spotted a reverberating light echo spreading across space. As a light pulse travels through space, it illuminates previously unseen material, revealing intricate structures resembling wood grain: https://webbtelescope.pub/422ET6Z #AAS245

What is the James Webb Space Telescope looking at right now? The atmosphere of a distant planet? A pillar of gas and dust shrouding newly formed stars? The Space Telescope Live has the answer! #AAS245 #NASAWebb

Two features of the supernova remnant Cassiopeia A show the power of #NASAWebb’s resolving power. The colorful inner shell shows tiny knots of gas and the smoky outer layer is where ejected matter rammed into the surrounding material: https://bit.ly/40IVTOS

Ever wonder what the secret ingredient is in your favorite dessert?

We can’t answer that, but we can share this planet formation recipe! It takes a high degree of precision and a lot of patience, but the result is pretty spectacular: https://bit.ly/3Cv3k2e

#NASARoman is on track to launch no later than May 2027! Recently, the Coronagraph Instrument, Optical Telescope Assembly, and Wide Field Instrument were attached to the telescope’s Instrument Center: https://go.nasa.gov/3ZQSnB1

New #NASAWebb data affirms Hubble findings and is causing researchers to rethink current models of planet formation in the universe’s early days: https://webbtelescope.pub/4guN0gE

It’s always nice to have someone in your corner, or in this case, space!

Scientists combined Hubble and #NASAWebb data to build a fuller picture of galaxy pair VV 191, which is composed of an elliptical galaxy at left and spiral at right: https://bit.ly/4esprnX

The Sombrero Galaxy stuns in a new portrait from #NASAWebb:

Young star FU Orionis is pretty shocking! Astronomers used Hubble to observe the sizzling star in ultraviolet light. At 16,000 kelvins, nearly three times our sun’s surface temperature, its disk is nearly twice as hot as prior models have calculated: https://bit.ly/4fZwSU5

A forming star in molecular cloud L1527 is the dot at the center. Why do near-and mid-infrared observations from #NASAWebb show such different views of its ejections? Find this answer, and more detail about Webb’s recent discoveries: https://webbtelescope.pub/3Yp62P5

The current form of the space triangle on the right is due to a gravitational tug-of-war with the galaxy to its left. These galaxies, captured by Hubble, are known as Arp 143. They have been bonded since they collided millions of years ago: https://bit.ly/3ASVQ8a

#NASAWebb observed Centaur 29P, one of the most active objects in the outer Solar System. Scientists discovered previously unseen jets of gas spewing from the centaur’s nucleus, potentially providing clues to its origin: https://bit.ly/4eAn2HC #astronomy

Astronomers using Hubble have discovered that the blowtorch-like jet blasting from a supermassive black hole at the core of galaxy M87 (left) seems to cause stars to erupt along its trajectory (right): https://bit.ly/3XwMsiu

Hubble hypnotizes with this detailed portrait of the Southern Pinwheel galaxy. All phases of the stellar life cycle are on display, from the youngest stars in glowing pink nebulas, to bright blue clusters, and the bubble-like remnants of supernovas. Credit: NASA, ESA, STScI.

Using Hubble, astronomers have found more black holes in the early universe than previously thought. They went black hole hunting in the landmark Hubble Ultra Deep Field, first taken in 2004, and in following observations to look for black holes: https://bit.ly/4efOl9Q

This pair of galaxies, NGC 2292 and NGC 2293, is beginning to collide, which has started the formation of new stars. These new stars appear like blue pearls in the dusty arm along the bottom.

The Kitt Peak National Observatory, a collection of ground-based observatories for nighttime visible and infrared astronomy, left, is in Arizona. It produced the image at right of the Pleiades cluster. More: https://noirlab.edu/science/programs/kpno #AURAPartners

With #NASAWebb nearly 1 million miles away, how is it able to send massive amounts of data from its observations back to Earth? It takes a little help from our friends at the Deep Space Network: https://webbtelescope.pub/3SO3AOk

Dive into the “Cosmic Reef” with Hubble! In 2020, this science visualization was part of Hubble’s 30th anniversary celebrations. Time flies!
