Mysterious little red dots threatened to overhaul modern cosmology—but new research may have solved the celestial conundrum.
so faraway stars look redder since they have a higher redshift. JWST is designed to look deep into the red and infrared spectrum, detecting old, distant galaxies better than any other telescope.
Space Telescope Science Institute sent out a tweet ... The quasar shown in the image is a 17th magnitude object at redshift z = 2.133 (10.6 billion light years away).
Einstein Probe's Wide-field X-ray Telescope (WXT) detected a burst of low-energy X-rays. Astronomers call such X-rays "soft," ...
Of all the mysteries that the massive James Webb Space Telescope has seen so far in the early universe, one of the strangest are objects that astronomers now call "little red dots." Like the ...
Space Telescope’s Ultra Deep Field ... Red light has the longest wavelength. The so-called “redshift” measured by JWST’s NIRCam for four galaxies was 10.38, 11.58, 13.20 and 12.63 ...
