If wormholes exist, they could magnify the light of distant objects by up to 100,000 times — and that could be the key to finding them, according to research published Jan. 19 in the journal Physical Review D. Wormholes are theoretical funnel-shaped portals through which matter (or perhaps spacecraft) could travel great distances. To imagine … Read more
The first stars in the cosmos may have topped out at over 10,000 times the mass of the sun, roughly 1,000 times bigger than the biggest stars alive today, a new study has found. Nowadays, the biggest stars are 100 solar masses. But the early universe was a far more exotic place, filled with mega-giant … Read more
Astronomers have spotted a runaway supermassive black hole, seemingly ejected from its home galaxy and racing through space with a chain of stars trailing in its wake. According to the team’s research, which was published April 6 in The Astrophysical Journal Letters (opens in new tab), the discovery offers the first observational evidence that supermassive … Read more
The elusive “Planet Nine,” which may or may not lurk in the outer reaches of the solar system, could be surrounded by a small swarm of potential moons, a new study reveals. What’s more, these moons could be the key to finding the missing planet. Planet Nine, if it exists, lurks beyond the orbit of … Read more
Astronomers have discovered an entirely new ring system within the solar system, and it’s located at such a great distance from its dwarf planet parent that it should be impossible. The ring surrounds Quaoar, which is around half the size of Pluto and located beyond Neptune. It is only the third ring to be found … Read more
For the first time, scientists have discovered a double-star system that is doomed to explode in a fiery “kilonova,” a precious-metal-creating blast caused by the merger of two stellar corpses. The kilonova — which will send gold, silver, platinum and other new heavy elements careening into space — won’t happen for millions of years. But … Read more
The moon exerts a previously unknown tidal force on the “plasma ocean” surrounding Earth’s upper atmosphere, creating fluctuations that are similar to the tides in the oceans, a new study suggests. In the study, published Jan. 26 in the journal Nature Physics, scientists used more than 40 years of data collected by satellites to track … Read more
Using a new machine-learning algorithm, scientists have picked up eight extraterrestrial signals that seem to bear the hallmarks of technology. The research, published Jan. 30 in the journal Nature Astronomy, doesn’t claim to have really found proof of intelligent aliens; a brief follow-up search for the signals detected in the study turned up only silence. … Read more
Scientists have made one of the most precise maps of the universe’s matter, and it shows that something may be missing in our best model of the cosmos. Created by pooling data from two telescopes that observe different types of light, the new map revealed that the universe is less “clumpy” than previous models predicted … Read more
Scientists have spotted an enormous, ‘alien’ comet streaking straight towards the sun. The 3.7 mile-wide (6 kilometers) space iceball, called 96P/Machholz 1, is thought to have come from somewhere outside our solar system, and is being monitored by the European Space Agency’s (ESA) Solar and Heliospheric Observatory (SOHO) spacecraft as it zips toward our star … Read more
