Universe

Gamma-ray bursts can be triggered by the explosion of a super massive star, collapsing into a black hole. From the vicinity of the black hole, powerful jets shoot in opposite directions into space, accelerating electrically charged particles, which in turn interact with magnetic fields and radiation to produce gamma rays.

Gamma-Ray Bursts With Record Energy Detected

The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialized telescopes, two international teams have registered the highest energy gamma rays ever measured from so-called gamma-ray bursts, reaching about 100 billion times as much…

Are Exiled Moons the Answer to Astronomical Mysteries?

Moons ejected from orbits around gas giant exoplanets could explain several astronomical mysteries, an international team of astronomers suggests. Researchers led by Mario Sucerquia, from the Universidad de Antioquia, Colombia, and Jaime Alvarado-Montes from Australia’s Macquarie University, modelled the likely…

What Delayed Earth’s Oxygenation?

Powering a massive biosphere on Earth, photosynthesis is the light-mediated reaction that converts carbon dioxide and water to carbohydrates and oxygen. About 2.3 billion years ago, this reaction led to a dramatic oxygenation of Earth’s atmosphere.

Could a Multiverse Be Hospitable to Life?

A Multiverse — where our Universe is only one of many — might not be as inhospitable to life as previously thought, according to new research. Questions about whether other…
