If Earth were an exoplanet, JWST would detect an intelligent civilization. A recent study published on preprint server arXiv revealed that if Earth were an…
Astronomers discover a star that could have exploded twice
of all types have a single explosion. However, now a group of astronomers believe they may have found a star that exploded twice as a…
Black holes keep ‘burping’ stars they destroyed years ago, and astronomers don’t know why
Astronomers made this discovery after years of observing black holes associated with tidal disturbance events (TDEs). TDE occurs when stars get too close to a…
Did this supernova explode twice?
All supernovae are exploding stars. However, the nature of supernova explosions is very different. One type, called supernova type 1a, is a binary star in…
What happened to all supermassive black holes?
A survey study using the James Webb Space Telescope has revealed that rapidly growing active galactic nuclei, or supermassive black holes, are not as common…
Supermassive exoplanets are denser than steel, scientists say
The newly discovered exoplanet exhibits so unusual properties that astronomers believe it must have undergone a giant impact some time ago. Although TOI-1853b is an…
Scientists discover and verify longest periodic exoplanet discovered by TESS
Scientists at the University of New Mexico (UNM) and the Massachusetts Institute of Technology (MIT) have discovered and validated two of the longest-period exoplanets TESS…
New method helps measure cosmological distances more accurately
A team of researchers from several Chinese universities and the University of Córdoba conducted a complex statistical analysis of about one million galaxies, and was…
Scorching Neptune-sized planet too big for astronomers to explain
Astronomers have unexpectedly discovered the most massive Neptune-like planet ever (more than four times the mass of Neptune in our solar system), but how the…
Matter Ejection Explains Strange High-low Mode Changes in Distant Millisecond Pulsars
The millisecond pulsar PSR J1023+0038 is known to switch between two luminance modes almost constantly, but this has been a mystery until now. PSR J1023+0038…
