The world, in perspective.

The astronomers, who set out to investigate star formation dynamics in the UBC 63 cluster using data from the European Space Agency’s (ESA) Gaia mission, were surprised to discover that UBC 63 actually consists of two clusters

Scientists have discovered a strange stellar pair more than 5,000 light-years away, where a dead star spinning every eight minutes produces mysterious radio pulses while orbiting a Sun-like star. The breakthrough also revealed massive magnetic storms on the companion star, offering fresh clues to one of astronomy's emerging mysteries.

The dwarf planet candidate, called ED138, appeared in telescope images and takes roughly 280 years to orbit the sun. Astronomers need to determine its size to properly classify it

The UK is unable to match the advanced surveillance and counter-surveillance programmes run by the US, China and Russia, but it is working with civilian astronomers to develop a way of monitoring spy satellites via ground-based telescopes

A breakthrough in telescope imaging could reveal countless alien worlds that have been hiding in plain sight. Scientists developed a new technique that uses a digital twin of the James Webb Space Telescope to remove the overwhelming glare of stars, making faint exoplanets two to 15 times easier to detect than with conventional methods. The technology has alr

<p>Archived observations appear to show a moving object in the far-distant outer solar system, but its reality is unclear</p>

Ian Griffin says the Swift Observatory has helped humans understand the biggest explosions in the universe.

The model, created by researchers at the Center for Astrophysics, Harvard & Smithsonian, and other institutions, captures how the first stars and black holes gradually illuminated the universe after millions of years of darkness

Lying beyond Pluto, 2026 ED138 could be as large as 1,500 kilometers in diameter. Astronomers are still working to confirm whether it meets the criteria for a dwarf planet.

Researchers study paintings and literature to uncover untold history of the works, sometimes finding themselves trying to discern celestial bodies from dust

Astronomers have uncovered evidence of a bizarre, potentially historic discovery: the first moon ever detected beyond our Solar System. Unlike familiar moons, this mysterious object is at least as massive as Jupiter and orbits a brown dwarf, which itself circles a star. The unusual arrangement challenges traditional definitions of planets and moons, leaving

The Sun’s seemingly peaceful regions are hiding a surprisingly complex magnetic world. Using a balloon-borne telescope high above Earth, scientists discovered delicate, thread-like magnetic structures woven through the solar atmosphere, apparently shaped by twisting motions on the Sun’s surface. They also mapped magnetic fields inside towering jets of solar

Very few night skies seen from the south of France during the summer of 1889 would match the scene on van Gogh's canvas. A new study argues that it could have been July 22

The universe formed 13.8 billion years ago, so this far-traveled burst of radio waves can help scientists learn more about the early cosmos. However, researchers still aren't sure what produces these strange flashes

<p>A misidentified constellation could revise the timeline for Vincent van Gogh&rsquo;s creation of his iconic painting</p>

White dwarf stars are too far from Earth to be observed directly. So, scientists reconstructed how they'd look to human eyes based on the wavelengths of light they emit and found a colorful array of objects that might appear yellow, purple or pink

Experts say that an oft-circulated anecdote about two royal astronomers drunkenly failing to foresee an eclipse thousands of years ago contains hints of truth

Scientists have achieved a major breakthrough in understanding the Universe’s earliest moments, measuring the amount of helium formed in the first five minutes after the Big Bang with unprecedented precision. Using one of the world’s most powerful telescopes, an international team studied 15 remarkably pristine galaxies that act as cosmic time capsules, pres
