Metal-poor stars are rare objects, as only a few thousand stars with iron [Fe/H] abundances below -2 have been discovered so far. By analyzing data…
Bizarre object 10 million times brighter than the sun defies physics, NASA says
In this illustration of an ultra-luminous X-ray source, two rivers of hot gas are pulled onto the surface of a neutron star. Strong magnetic fields,…
Scientists map gusty winds in a far-off neutron star system
Winds from the black hole accretion disk can affect the environment in the vicinity of these objects and neutron stars. This was affirmed by a…
NASA Study Helps Explain Limit-Breaking Ultra-Luminous X-Ray Sources
These objects are more than 100 times brighter than they could be. Observations from the agency’s NuSTAR X-ray telescope support a possible solution to this…
Hubble unexpectedly finds a double quasar in a distant universe
The early universe was a bustling place where galaxies often collided with each other and even merged. Using NASA’s Hubble Space Telescope and other space-based…
New revelation: the James Webb Space Telescope located the most distant galaxy detected to date
JADES-GS-z13-0, the most distant galaxy captured by the James Webb telescope The James Webb Space Telescope located the most distant galaxy detected to date, created…
They reveal how the brightest gamma-ray burst of all time was
NASA scientists detected the brightest gamma-ray burst on record, which occurred 2 billion light-years from Earth. The “brightest ever” gamma-ray burst (GRB) is what astronomers…
Radio signal from a rocky planet increases chances of discovering habitable worlds
An international research team has discovered a possible rocky, Earth-like exoplanet (or exoplanet) called YZ Ceti b could have a magnetic field. It is the…
A distant radio signal indicates that a rocky exoplanet could have a magnetic field
A planet’s magnetic field can shield its atmosphere from particles spewed out by its star. The fact that a planet has a strong magnetic field…
Two rare black holes discovered very close to Earth
These two black holes are rare because of the great distance that separates them from their star, preventing them from swallowing it. This also makes…
