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...
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 ...
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...
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...
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...
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...
IXPE quickly observes aftermath of exceptional cosmic blast
Dec 27, 2022 (SPX)
Michela Negro, a postdoctoral research assistant at the University of Maryland Baltimore County and NASA's Goddard Space Flight Center in Greenbelt, Maryland, c...
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. ...
Astronomers identify the ancient heart of the Milky Way galaxy
Dec 22, 2022 (SPX)
Our home galaxy, the Milky Way, gradually formed over nearly the entire history of the Universe, which spans 13 billion years. Over the past decades, astronomer...
Chile's ALMA observatory resumes work after cyberattack
Dec 21, 2022 (AFP)
ALMA, the world's most powerful telescope for observing molecular gas and dust, studies the building blocks of stars, planetary systems, galaxies and life itsel...
Cosmological enigma of Milky Way's satellite galaxies solved
Dec 20, 2022 (SPX)
These satellite galaxies exhibit a bizarre alignment - they seem to lie on an enormous thin rotating plane - called the "plane of satellites" This seemingly unl...
Webb Space Telescope reveals previously shrouded newborn stars
Dec 20, 2022 (SPX)
The published research in the December issue of the Monthly Notices of the Royal Astronomical Society offers a glimpse of what astronomers will find with Webb's...
New study confirms the light from outside our galaxy brighter than expected
Dec 18, 2022 (SPX)
The research team analyzed hundreds of images of background light taken by the Long-Range Reconnaissance Imager (LORRI) on NASA's New Horizons mission to calcul...
Astronomers may have uncovered how galaxies change their shape
Dec 18, 2022 (SPX)
Ever since the Hubble Sequence, that classifies galaxy morphologies, was invented in 1926, astronomers have been refining our understanding of galaxy evolution ...
FAST reveals unprecedented details of the Milky Way
Dec 13, 2022 (SPX)
The diffuse hydrogen gas radiates a spectral line with a frequency of around 1420 MHz. Some dense hydrogen atoms gather to form clouds of molecular hydrogen, an...
Scientists find new hints that dark matter could be made up of dark photons
Dec 13, 2022 (SPX)
intergalactic filaments are hotter than predictions from hydrodynamical simulations of the standard model of structure formation. "Since dark photons would be a...
Astronomers report most distant known galaxies, detected and confirmed by JWST
Dec 12, 2022 (SPX)
Initial observations from JWST yielded several candidate galaxies at extreme distances, as had earlier observations with the Hubble Space Telescope. Now, four o...
