When it comes to the life of a big-time movie star like Karen Gillan, one often gets a leg up in the presentation department. That's because a celebrity is often followed around by a small crew of stylists to get them looking beautiful for all their public appearances. However, the Guardians of the Galaxy alum recently went rogue right before a Q&A in London, as she shared a video that showed her cutting her own hair. And, in all honesty, I can totally relate to the chaotic energy the social media clip gives off.The…

June Wan/ZDNETIf you've been eyeing the Samsung Galaxy S24 for its fancy new AI features like Live Translate, Photo Assist, and Circle to Search, you may be wondering if they're really worth the upgrade.That decision is getting a little easier, as you can now test-drive Galaxy AI on any Android phone to see if it's worth the hype.Also: I tried the Samsung Galaxy Ring and it beats the Oura in 2 meaningful waysSamsung believes its AI-powered features are better experienced than explained. In an attempt to woo users to…

In December 2023, Microsoft launched the Copilot app for Android, which offers many useful AI-powered features. It can answer your questions, write content for you, and create images for you among other things. Now, Microsoft has released a new beta version of the app (version 27.9.420225014) which brings the ability to set Copilot as the default digital assistant app on your device, letting you access Copilot by just long-pressing the home/power button or swiping diagonally from the corner of the screen. You can now…

This artist’s illustration shows a cross-section of the supermassive black hole and surrounding material in the center of our galaxy. The black sphere in the center represents the event horizon of the black hole, the point of no return from which nothing, not even light, can escape. Looking at the spinning black hole from the side, as depicted in this illustration, the surrounding spacetime is shaped like an American football. The yellow-orange material to either side represents gas swirling around the black hole. This…

A supermassive monster lurks at the center of our galaxy, and astronomers have now discovered that it’s spinning so fast it’s warping the very fabric of spacetime into a football shape.According to Einstein’s general theory of relativity, mass bends spacetime, a four-dimensional “fabric” that pervades the universe, and the effect is what we experience as gravity. It happens with any amount of mass – you yourself are bending spacetime right now – but it’s barely noticeable until you’re dealing with extremely massive…

The image, taken with ESO’s Very Large Telescope in Chile, shows a high-resolution view of the innermost parts of the Milky Way. In the new study, the researchers examined the dense nuclear star cluster shown in detail here. Credit: ESOThrough the study of detailed data obtained from a powerful ten-meter telescope located in Hawaii, a team of scientists at Lund University in Sweden have made significant discoveries regarding three stars situated in the central region of the Milky Way galaxy. These stars were found to be…

Manitoba), Nathan Deg (Queen’s U.) & WALLABY Survey, CSIRO / ASKAP, NAOJ / Subaru TelescopeGalaxy NGC 4632 harbors a concealed feature invisible to optical telescopes. This galaxy is encircled by a cool hydrogen gas ring that orbits perpendicularly to its spiral disk. Polar ring galaxies, known for such unique formations, are…

Vampires may be lurking in space in the most ironic way possible – by hiding evidence of their kills in broad daylight.What's more, just as Dracula had a diabolical assistant, these life-draining stars might be getting a little help from another nearby object.A study of some of the brightest, hottest stars in the Milky Way suggests theorized binary systems comprizing of a rapidly-spinning star feeding off a companion might actually be trinary systems, with a drained husk of one star lurking in the larger star's glow and…

Compared to some other galaxies out there, the supermassive black hole at the heart of the Milky Way isn't a particularly active one. It's not guzzling down scads of material, and it's not blasting giant jets of plasma into space.Even a relatively peaceful supermassive black hole, however, is a wild, savage beast, and our own – named Sagittarius A* – has been recorded doing some pretty strange things. And now there's a new one: astrophysicists Gustavo Magallanes-Guijón and Sergio Mendoza of National Autonomous University…

Astronomers have just discovered one of the rarest stars in our galaxy. These types of stars are known as white dwarf pulsar stars, and they’re so rarely seen that only one other is known to exist in the entire Milky Way. Now, that original white pulsar, known as AR Scorpii, is joined by what astronomers have called J1912-4410. The newly discovered white pulsar is located just 773 light-years away from Earth and was recently discovered by a group of astronomers and astrophysicists working with the University…
