The next explosion is expected to occur from now through September. “The star system, normally magnitude +10, which is far too dim to see with the unaided eye, will jump to magnitude +2 during ...
With a rare star explosion expected any day now, astrophysicists are relying on a community of hobbyists with backyard telescopes to tell them when it erupts. ... July 29, 2024 at 6:00 AM.
The last time this particular star system erupted was in 1946, Schaefer said, and another eruption will likely not occur for another 80 years or so. Astronomers around the world are monitoring ...
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.
T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a binary star and a recurrent nova about 3,000 light-years (920 pc) away in the constellation Corona Borealis. [11] It was first discovered in outburst in 1866 by John Birmingham , [ 12 ] though it had been observed earlier as a 10th magnitude star. [ 13 ]

One of the most successful space missions to date, Swift, was launched in 2004 and as of May 2024 is still operational. [41] [42] Swift is equipped with a very sensitive gamma-ray detector as well as on-board X-ray and optical telescopes, which can be rapidly and automatically slewed to observe afterglow emission following a burst.
