Observations by NASA’s NuSTAR X-ray telescope give astronomers new clues about the brightest and most energetic gamma-ray burst ever detected. When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts...

While searching for the origins of a powerful gamma-ray burst (GRB), an international team of astrophysicists may have stumbled upon a new way to destroy a star. Although most GRBs originate from exploding massive stars or neutron-star mergers, the researchers concluded that GRB 191019A instead came...

Using the Hubble Space Telescope (HST) and Jansky Very Large Array (VLA), astronomers have investigated an ultra-diffuse galaxy known as UGC 9050-Dw1. Results of the study, published June 9 on the pre-print server arXiv, yield important insights into the properties of this galaxy. Ultra-diffuse...

Near the center of the Milky Way Galaxy sits an immense object that astronomers call Sagittarius A*. This “supermassive” black hole may have grown in tandem with our galaxy, and it’s not alone. Scientists suspect that similar behemoths lurk at the heart of almost all large galaxies...

When multiple NASA telescopes observe the same cosmic region, the universe’s true colors are revealed. Four composite images deliver dazzling views from NASA’s Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. Each image combines Chandra’s X-rays...

As part of DARPA’s SafeDocs program, JPL data scientists have amassed 8 million PDFs that can now be used for further study in order to make the internet more secure. NASA’s Jet Propulsion Laboratory is well known for landing rovers on Mars, exploring the solar system with robotic probes, and...

According to the head of the Space Research Laboratory at the Egyptian National Research Institute of Astronomy and Geophysics (NRIAG), Prof. Dr Rasha Mohamed-Fathy Ghoneim, Egypt, in collaboration with China, is planning to construct the second-largest global monitoring station. This facility will...

Sodium chloride, better known as table salt, isn’t exactly the type of mineral that captures the imagination of scientists. However, a smattering of tiny salt crystals discovered in a sample from an asteroid has researchers at the University of Arizona Lunar and Planetary Laboratory excited...
