A single bright star in the constellation of v Indus, visible from the southern hemisphere, has revealed new insights on an ancient collision that our galaxy, the Milky Way, underwent with another smaller galaxy called Gaia-Enceladus early in its history.  (Image: via   Troy Oakes Photography  )

TESS Dates an Ancient Collision With Our Galaxy

An international team of scientists led by the University of Birmingham adopted the novel approach of applying the forensic characterization of a single ancient, bright star called ν Indi as a probe of the history of the Milky Way.  Stars carry “fossilized…

Illustration depicting a Type I X-ray burst. The explosion first blows off the hydrogen layer, which expands and ultimately dissipates. Then rising radiation builds to the point where it blows off the helium layer, which overtakes the expanding hydrogen. Some of the X-rays emitted in the blast scatter off of the accretion disk. The fireball then quickly cools and the helium settles back onto the surface. (Image: NASA's Goddard Space Flight Center / Chris Smith (USRA))

NASA’s NICER Catches Record-Setting X-Ray Burst

NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station detected a sudden spike of X-rays at about 10:04 p.m. EDT on August 20. The burst was caused by a massive thermonuclear flash on the surface of a pulsar, the…
