Gravitational waves from massive black holes challenge current astrophysical models The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. The powerful merger produced a final black hole approximately 225 times the mass of our Sun. The signal, designated GW231123, was detected during the fourth observing run of the LVK network on November 23, 2023. LIGO, the Laser Interferometer Gravitational-wave Observatory, made history in 2015 when it made the first-ever direct detection of gravitational waves, ripples in space-time. In that case, the...

Scientists predict up to 100 invisible galaxies may orbit the Milky Way, hiding just beyond our current detection limits. Credit: Shutterstock *********************************************************************** Astronomers may be on the verge of uncovering a long-lost galactic population. Using ultra-high-resolution simulations and sophisticated modeling, researchers at Durham University predict that the Milky Way could be surrounded by up to 100 previously undetected satellite galaxies. These faint, elusive “orphan galaxies” may have been stripped of their dark matter halos, making them nearly invisible to current telescopes. But with the advent of powerful new instruments like the Rubin Observatory, scientists believe we’re finally approaching the ability...

The Eagle takes flight this July. Look east after dark to find Aquila, the soaring constellation anchored by Altair, while Mars glows in the west and Venus and Jupiter greet the sunrise. Credit: Shutterstock July’s skies offer a feast: Mars glows at dusk while Mercury peeks out briefly, Venus blazes before dawn, and Jupiter joins it for a photogenic pairing. Saturn lingers past midnight, and the Moon stages close encounters with Mars and the morning planets. Sixty years after Mariner 4’s trailblazing flyby, stargazers can celebrate by tracing Aquila the Eagle soaring overhead, using bright Altair to sketch its wings...

That’s the conclusion reached by one researcher from the University of North Carolina: black holes can’t exist in our Universe — not mathematically, anyway. “I’m still not over the shock,” said Laura Mersini-Houghton, associate physics professor at UNC-Chapel Hill. “We’ve been studying this problem for a more than 50 years and this solution gives us a lot to think about.” In a news article spotlighted by UNC the scenario suggested by Mersini-Houghton is briefly explained. Basically, when a massive star reaches the end of its life and collapses under its own gravity after blasting its outer layers into space —...

You can manipulate a black hole as much as you like but you’ll never get rid of its event horizon, a new study suggests. This may sound a little odd, the event horizon is what makes the black hole, well… black. However, in the centre of a black hole, hidden deep inside the event horizon, is a singularity. A singularity is a mathematical consequence, it is also a point in space where the laws of physics do not apply. Mathematics also predicts that singularities can exist without an associated event horizon, but this means that we’d be able to physically...

WASHINGTON (Reuters) - A supermassive black hole appears to be homeless in the cosmos without a galaxy to nestle in, Hubble Space Telescope scientists reported on Wednesday. Most monster black holes lurk at the heart of massive galaxies, slurping up matter from the galactic center with a pull so strong that nothing, not even light, can escape. But a team of European astronomers reported in the journal Nature that a particular black hole some 5 billion light-years away has no evidence of a host galaxy. A light-year is about 6 trillion miles, the distance light travels in a year. The...

A dangerous misconception exists in the field of ufology that there are no astronomers who have seen UFOs. But nothing could be farther from the truth. In fact, there is a long list of famous astronomers who have had remarkable UFO sightings. In 1952, J. Allen Hynek, the astronomical consultant for the Air Force’s Project Blue Book held a conference with a group of astronomers. He asked about UFOs and received some shocking responses. “Over forty astronomers were interviewed,” he said, “of which five had made sightings of one sort or another. This is a higher percentage than among the...

Astronomers have spotted a new comet, moving on a trajectory that indicates that it whizzed into our solar system from interstellar space and is just passing through. It's only the third time scientists have discovered this kind of visitor from outside our solar system. The first two, 'Oumuamua and Comet Borisov, intrigued astronomers because of the chance to observe pieces from another star system beyond our own. "This is like our chance to randomly sample what's going on in the rest of the galaxy," University of Oxford astrophysicist Chris Lintott recently told NPR, saying he and most other researchers really...

For only the 3rd time in history, astronomers have found an interstellar object hurtling through our solar system...The Minor Planet Center (MPC) confirmed its new designation on July 2, 2025, as 3I/ATLAS, or C/2025 N1. The MPC also said:There are tentative reports of cometary activity … with a marginal coma and a short 3-arcsecond tail....We are currently being visited by what appears to be a comet from another solar system...We only know of two other interstellar objects that have entered into our solar system before, 'Oumuamua and Comet 2I/Borisov. The nature of 'Oumuamua is still a matter of debate, and...

NASA's James Webb Space Telescope recently detected a planet that could possibly sustain life based on temperature readings, which has a mass approximately 100 times the size of Earth. The planet, which astronomers believe is orbiting a young red dwarf star approximately 34 light years away, has been dubbed TWA 7b and is roughly the size of Saturn. An initial analysis suggests the planet has a temperature of near 120 degrees Fahrenheit, which is warm enough to support life. Scientists believe life can grow and reproduce starting at about 5 degrees Fahrenheit and as high as 251 degrees Fahrenheit, per...

A meteorite, complete with shock wave, light trail, and flight noises (rumbles, light a train or close airplane) struck the ground northeast of Atlanta this afternoon, 26 June 2025. Impact was visible from dash cameras in vehicles on I85 near the South Carolina border. Meteor is any solid object hitting the atmosphere but burning up before it hits the ground. A meteorite is a rocky solid that survives its flight through the atmosphere and hits the ground as a solid. Damage is unknown, some reports claim a house was struck.
