Astronomers Have Never Detected Merging Supermassive Black Holes. That Might Be About to Change
Gravitational wave astronomy currently can only detect powerful rapid events, such as the mergers of neutron stars or stellar mass black holes. We’ve been very successful in detecting the mergers of stellar mass black holes, but a long-term goal is to detect the mergers of supermassive black holes.
Even Though They’re Bigger, Generation 2 Starlinks are Fainter than Gen 1
We’ve filed plenty of reports here at UT warning about the potential impact of Starlink and similar satellites on the field of astronomy. We’ve gone so far as to point out that the granddaddy of space-based telescopes – Hubble – has already had some of its images tarnished by passing Starlink satellites. However, SpaceX has been aware of the problem and is working to limit their product’s brightness. The recently launched Gen2 satellites seem to have made a significant step forward – research from a team of amateur astronomers finds that the new Gen2 Starlinks are more than 10x fainter than previous Gen1 iterations.

New Space companies join Copernicus
With commercial companies playing an increasingly important role in creating a dynamic and innovative space industry, nine New Space satellite data suppliers have joined the Copernicus programme as ‘Contributing Missions’. Today, at the Le Bourget Paris Air Show, ESA and the European Commission further embraced the era of New Space by welcoming these nine companies into the fold and celebrating the contribution they will make in monitoring our changing world.
A dynamic form of dark energy may explain strange radiation signal from the early universe
We may have already found evidence of an evolving, dynamic kind of dark energy, in the form of the radiation emitted when the first stars appeared in the universe.
Even Lonely Black Holes Need to Eat
Astronomers have found supermassive black holes in smaller galaxies are actually more likely to light up when they’re isolated in vast, cosmic voids.

Euclid: ESA’s mission into the unknown
Video: 00:03:29
ESA’s Euclid mission is designed to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.
Astronomers See the Same Supernova Four Times Thanks to a Gravitational Lens
Measuring cosmic distances is challenging, and astronomers rely on multiple methods and tools to do it – collectively referred to as the Cosmic Distance Ladder. One particularly crucial tool is Type Ia supernovae, which occur in binary systems where one star (a white dwarf) consumes matter from a companion (often a red giant) until it reaches the Chandrasekhar Limit and collapses under its own mass. As these stars blow off their outer layers in a massive explosion, they temporarily outshine everything in the background.
