• Astronomers discover a potentially habitable planet just 25 light-years away. 'This one is exciting'

  A potentially habitable rocky world has been found in the habitable zone around a red dwarf just 25 light-years from us.However, faced with a hostile wind of radiation from its host star, it remains unclear whether this new exoplanet supports an atmosphere, or the possibility of life. Nevertheless, astronomers are celebrating the discovery. "This one's exciting," said Paul Robertson of the University of California, Irvine, in a statement. "It's one of our closest cosmic neighbors.

• How to invade planet Earth: An alien's guide to bringing the human race to its knees

  It looks there for the taking, doesn't it? The third rock from the sun just sitting there, all defenceless, run by squabbling politicians ruling over a human race who'd rather be sharing "get ready with me" videos than vigilantly watching the skies as they should be.But next time you set your sights on invading planet Earth, remember that it's easier said than done. Some of the mightiest alien attack forces in existence have met their match in this particular corner of the Milky Way, as the resi

• July full moon 2026: When, where and how to see the Buck Moon

  02-07-2026 14:00 via space.com
  
  The July full moon occurs at 10:36 a.m. EDT (1436 GMT) on July 29, when the lunar disk appears fully lit as it shines opposite the sun in Earth's sky. The July full moon is often called the "Buck Moon", to reflect the time of the year when young male deer grow out their antlers in the northern hemisphere and is the first full moon of summer, occurring soon after the 2026 summer solstice. When to see the July full moonLook to the east at sunset on July 29 to catch the full Buck Moon as it climbs

• In 1776, the moon was a clock, a calendar and a streetlight — and it was 31 feet closer to Earth

  02-07-2026 12:00 via space.com
  
  After Americans declared independence on July 4, 1776, a waning gibbous moon rose in the night sky. To the people celebrating the birth of a new nation, it would have looked much the same as the moon we see today. But there was one subtle difference: 250 years ago, the moon was about 31 feet (9.4 meters) closer to Earth than it is now."The moon is currently drifting away from Earth at a rate of about 3.8 centimeters [1.5 inches] per year, which is coincidentally roughly the same speed at which h

• Sun fires off 10 solar flares in 24 hours as multiple Earth-bound CMEs raise northern lights hopes for July 4 weekend

  02-07-2026 11:53 via space.com
  
  Heads up aurora chasers! The sun has been very busy. After unleashing an X1.1 solar flare on June 30, the sun continued its outburst by firing off 10 M-class solar flares in 24 hours! Several of these eruptions were accompanied by coronal mass ejections (CMEs) that appear to be at least partially Earth-directed. Exactly how many of these solar storms will reach Earth (and how effective they will be) is still being calculated, but space weather forecasters say the coming days could bring heighten

  Steven Spielberg's latest sci-fi movie, Disclosure Day, has finally hit cinemas worldwide. It's been eight years since the iconic director released a movie in this genre, re-entering his UFO era with a twisted alien thriller. To mark his momentous return to sci-fi cinema, we've taken time to gaze across his entire sci-fi slate, ranking them from worst to best. We use the term 'worst' lightly, though. Spielberg is a movie legend after all. To date, he's directed over 30 films during his illustrio

• This weird 'hot Jupiter' exoplanet has a hotspot in the wrong place, and astronomers aren't sure how

  01-07-2026 20:00 via space.com
  
  Hot Jupiters are some of the most extreme planets in the universe, blazing gas giants like Jupiter or Saturn that exist so close to their stars that they complete orbits in a matter of days. Now, new research may rewrite the definition of these planets that make the solar system look a little bit mundane.The extrasolar planet, or exoplanet, at the heart of this rethink is CoRoT-2 b, a world with 3.5 times the mass of Jupiter and 1.5 times the size of our solar system's largest planet, located ar

• The growing number of satellites in orbit could soon make telescopes obsolete. 'For astronomy, this would obviously be catastrophic'

  01-07-2026 18:56 via space.com
  
  If the number of satellites in Earth's orbit exceeds 100,000, humanity may lose its ability to study the universe from the planet's surface. That's the conclusion of a study conducted by astronomers from the European Southern Observatory (ESO) which warns that if existing plans to deploy a million orbiting data centers and tens of thousands sun-reflecting mirrors were to come to fruition, the world's most cutting-edge astronomical telescopes may as well be mothballed."We can reach conditions whe

• In 1776, the solar system only had 6 planets. Now, it has 8. Does it end there?

  Over the past 250 years, the number of "planets" in our solar system has ranged from six to nine — and, briefly, even 11 — depending on what astronomers knew at the time and how they defined a planet. As the United States prepares to celebrate its 250th anniversary, that changing tally offers a unique lens on humanity's evolving understanding of the cosmos since 1776.Throughout history, astronomers have discovered new worlds, identified entirely new classes of celestial objects and r

• Mars may have once been filled with seas of magma that made the Red Planet habitable

  30-06-2026 20:00 via space.com
  
  Deep oceans of magma once sloshed about inside the crust of Mars, seismic measurements taken by NASA's InSight mission suggest. The marsquakes detected by InSight show a boundary 15 miles (24 kilometers) deep between two different types of rock that were formed by enormous pools of magma. The presence of these magma pools could completely change what we thought we knew about the early development of Mars.Already, scientists say the discovery could change what we know about the history of Mars.

  Star Fox 64 is the Nintendo game that refuses to fade away, and we're not complaining, especially when the new Switch 2 remake — simply titled Star Fox — amplifies its replay value and expands the original vision with a bunch of new content.Roughly a decade ago, Star Fox Zero almost killed the franchise for good. The ill-fated Wii U entry's structure and plot stuck staggeringly close to Star Fox 64 (Lylat Wars for us PAL gamers), but no one could definitely answer if it was a remake,
