NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive black hole at the center of our Milky Way galaxy, observing a steady ...
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
The Webb observations mark the longest, most detailed look researchers have been able to make around the Milky Way’s central black hole, called Sagittarius A*, building on past evidence of its ...
Webb will far surpass both those telescopes, being able to see many more and much older stars and galaxies. [169] Observing in the infrared spectrum is a key technique for achieving this, because of cosmological redshift, and because it better penetrates obscuring dust and gas. This allows observation of dimmer, cooler objects.
The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] The first letter, "Y", indicates that the asteroid was discovered in the second half-month of December (16 to 31 December), and "R 4" indicates that it was the 117th provisional designation to be assigned in that half-month.
Images of NGC 3132 reveal two stars close together within the nebulosity, one of 10th magnitude, the other 16th, located about 1.7″ away from the central star.The central star of the planetary nebula is a white dwarf, and is the fainter of the two stars.
In Webb's First Deep Field, the cluster is composed primarily of the fuzzy blobs seen across the center of the image below. The gravitational pull of a galaxy cluster is so strong that it can bend ...
JADES-GS-z14-0 was observed using the James Webb Space Telescope's Near-Infrared Spectrograph (NIRSpec) in 2024, [3] and it measured a redshift of 14.32. [4] Its age, size, and luminosity added to a growing body of evidence that current theories of early star and galaxy formation are incomplete.
