Can We Predict if a System Will Have Giant Planets?
Prediction is one of the hallmarks of scientific endeavors. Scientists pride themselves on being able to predict physical realities based on inputs. So it should come as no surprise that a team of scientists at Notre Dame has developed a theory that can be used to predict the existence of giant planets on the fringes of an exoplanetary system.
The Evidence is Building that Dark Matter is Made of Axions
There’s some potentially big news on the hunt for dark matter. Astronomers may have a handle on what makes this mysterious cosmic stuff: strange particles called “axions.”
Europe's most dangerous 'supervolcano' could be creeping toward eruption, scientists warn
Italy's Campi Flegrei is showing some troubling early warning signs, but scientists caution that its eruption is far from certain.
Quantum computers could overtake classical ones within 2 years, IBM 'benchmark' experiment shows
A new experiment by IBM computers shows that quantum computers could soon outperform classical digital computers at practical tasks in the next two years.
Stephen Hawking wanted scientists to 'make black holes' on Earth. Physics says it's possible.
When Stephen Hawking and I visited the Large Hadron Collider, he hoped for an unexpected physics breakthrough. His dreams may not be impossible.
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.
Rocket Lab's modified Electron rocket HASTE achieves first suborbital launch
Rocket Lab's Hypersonic Accelerator Suborbital Test Electron (HASTE) rocket blasted off from NASA's Wallops Flight Facility on Saturday, June 17.

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.

How do lightsabers work?
Lightsabers are the most iconic Star Wars weapons, but their mechanics and complete history aren’t crystal clear. Here’s everything you need to know about them.
Europe's BepiColombo spacecraft to zoom within 150 miles of Mercury in close flyby today
Europe's Mercury probe BepiColombo will take a close look at its target planet on Monday(June 19), and we can expect some exciting new images soon after that.
NASA recognizes Juneteenth with ceremonial flag-raising (photos)
NASA held a flag-raising ceremony on Thursday (June 15) to recognize the Juneteenth holiday.
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.
