The Fermi Gamma-ray Space Telescope of NASA has been scanning for gamma-ray bursts (GRBs)—the most glowing explosions in the Universe—from the last 10 Years. A new directory of the most vigorous bursts provides researchers with the most recent approaches to study how they work.
Green dots visible in the observed area of LAT denote the positions of 186 GRBs. In most of the cases, GRBs arise when the fuel of a massive star completely exhausts and it collapses to form a black hole. While in the few cases, GRBs occur by the merger of two neutron stars.
The scientists used five record-setting and fascinating events from the catalog of Large Area Telescope to understand thoroughly about GRBs. Those five events are GRB 081102B, GRB 160623A, GRB 130427A, GRB 080916C, and GRB 090510.
The data of the catalog has recently been published in the journal The Astrophysical Journal.
On a similar note, the astronauts and scientists believed that Jupiter’s moon, Europa, comprised of an ocean that might be underneath the thick icy crust. According to a recent study, in which the researchers scanned the Jupiter’s moon with the Hubble Space Telescope Imaging in infrared light, they found a substance, which resembled irradiated sodium chloride, commonly called table salt.
In one of the earlier studies related to Jupiter’s moon, a scientist at NASA’s Jet Propulsion Laboratory, Kevin Hand, visualized the ocean salt samples under Europa environment, by simulating such conditions in the laboratory. He bombarded the samples with the radiations and found that sodium chloride sample turned yellow, which appears similar to the yellow patches at the specific region on the moon, Tara Regio. The study suggests that the moon might have abundant of sea salt.
As Tara Regio was formed at the end compared to the remaining surface of the moon, researchers consider the salt derived from the interaction between the moon’s surface and the underneath ocean.
