The enduring stellar lifecycle in 30 Doradus
Jan 11, 2023 (SPX)
NASA's Chandra X-ray Observatory has frequently looked at 30 Doradus over the lifetime of the mission, often under the direction of Dr. Leisa Townsley who passe...
Webb reveals links between galaxies near and far
Jan 10, 2023 (SPX)
"With detailed chemical fingerprints of these early galaxies, we see that they include what might be the most primitive galaxy identified so far. At the same ti...
IXPE Team Profile; LASP at Colorado-Boulder
Jan 09, 2023 (SPX)

Webb reveals Milky Way-like galaxies in early universe
Jan 06, 2023 (SPX)
Prior to JWST, images from the Hubble Space Telescope had never detected bars at such young epochs. In a Hubble image, one galaxy, EGS-23205, is little more tha...
Strengthening electron-triggered light emission
Jan 06, 2023 (SPX)
Now, researchers at MIT and elsewhere have come up with an innovative way to make much stronger interactions between photons and electrons possible, in the proc...
Serpent in the sky captured with ESO telescope
Jan 05, 2023 (SPX)
When the ancients looked up at the night sky they saw random patterns in the stars. The Greeks, for instance, named one of these "constellations" Serpens, becau...
Hubble finds that ghost light among galaxies stretches far back in time
Jan 05, 2023 (SPX)
The nagging question for astronomers has been: how did the stars get so scattered throughout the cluster in the first place? Several competing theories include ...
A light source that produced two entangled light beams
Jan 04, 2023 (SPX)
Interest in studying this kind of phenomenon is due to the significant potential for applications in encryption, communications and quantum computing. The diffi...
LHAASO's dark matter search places tighter constraints on dark matter's lifetime
Jan 03, 2023 (SPX)
The study, entitled "Constraints on heavy decaying dark matter from 570 days of LHAASO observations," was recently published as a highlight letter in Physics Re...
Mysterious gamma-ray emitting bubbles around the center of our Galaxy explained
Jan 01, 2023 (SPX)
The universe is full of massive celestial objects which are yet to be explained. One of these are the "Fermi bubbles," so-called because they were first discove...
NASA, SpaceX to Study Hubble Telescope Reboost Possibility
Dec 29, 2022 (SPX)
There are no plans at this time for NASA to conduct or fund a dedicated Hubble servicing mission. The Request for Information will remain open until Tuesday, Ja...
Precise FAST observations reveal circular polarization in active repeating fast radio bursts
Dec 29, 2022 (SPX)
Fast radio bursts (FRBs) are the most luminous radio flashes in the universe. The estimated equivalent energy of one FRB event can rival that of the Sun in a wh...
Webb telescope promises new age of the stars
Dec 27, 2022 (AFP)
The most powerful observatory sent into space succeeded the Hubble telescope, which is still operating, and began transmitting its first cosmic images in July. ...
