18 Hours Ago   When you gaze at the sky on a clear night, you can easily spot countless stars shining bright. Most of them look pretty much identical, aside from varying brightness, but when NASA's Hubble Space Telescope zooms in on a distant object, it can see it for what it truly is.

Yesterday   If there's one thing you can say about Elon Musk it's that he's never lacked ambition. He's founded a number of successful companies, and with SpaceX he's pushed science forward by lowering the cost of entry for satellite launches and opened up new possibilities for researchers.

2 Days Ago   SpaceX might be the worldwide leader in commercial spaceflight — and get a whole lot of attention because of it — but it's not the only private company vying for a slice of the pie.

2 Days Ago   Scientists have a pretty good handle on the life cycle of various stars. They know the types of stars that are likely to die in fiery supernova blasts, and they know that not all supernova are created equal.

2 Days Ago   Cave bears no longer exist. They went extinct tens of thousands of years ago, and all we have left of the massive ancient creatures are fossils.

3 Days Ago   The scheduled launch date of NASA's Mars 2020 mission is rapidly approaching, and with less than a year to go, it's truly crunch time for NASA and its partners.

3 Days Ago   You might not think we have much in common with a race of ancient people that died out tens of thousands of years ago, but modern humans actually share a number of similarities with neanderthals.

3 Days Ago   Major airlines all over the globe have a serious problem on their hands, and it's not just the fact that the Boeing 737 Max remains grounded months after a pair of deadly crashes claimed hundreds of lives.

3 Days Ago   Conor McGregor, former two-division UFC champion and noted hater of mass transit, "retired" from the sport of MMA back in March of this year. It was the second time he had retired, as well as the second time he had retired via Twitter.

3 Days Ago   By now we all know how devastating a heavy smoking habit can be for our overall health, but the air wafting around your neighborhood might not be all that much better.

4 Days Ago   Jupiter has long been hailed as the mighty "king of planets" thanks to its massive size compared to most of the other planets in our solar system.

4 Days Ago   Studying distant objects in space can be tricky for astronomers, especially when those objects begin to do unexpected — and unexplainable — things. Neutron stars are thought to be the most dense objects in space, and scientists have a pretty good handle on how they form.

4 Days Ago   If the thought of an asteroid careening toward Earth keeps you up at night you can breathe a little easier today, as scientists have now ruled out a potential impact from the space rock known as 2006 QV89.

4 Days Ago   Facial recognition technology has come a long way in recent years, and today many smartphone users rely on face unlock features to keep their devices secure.

4 Days Ago   The James Webb Space Telescope is going to be an incredible tool for scientists to peer deep into space, returning information that could teach us a lot about our universe and our place in it.

5 Days Ago   NASA's OSIRIS-REx spacecraft is currently hanging out around the asteroid known as Bennu. It's been there for months, taking photos and scanning the asteroid's surface to get a better idea of exactly what dangers the probe might face when it eventually touches down.

5 Days Ago   Today, scientists dream of one day building settlements on the Moon and even Mars, where research can be conducted and human travelers can live safely for months or years.

5 Days Ago   Sending a spacecraft to Mars is no easy feat, but landing it on the Red Planet without making a crater is equally challenging. The European Space Agency knows that all too well, and a recent parachute test has raised serious questions about whether the ExoMars 2020 mission will remain on schedule.

5 Days Ago   Spotting a bear on a hiking trail or wandering around your rural back yard can be somewhat frightening, but most of the time they'd just assume ignore your presence entirely.

5 Days Ago   Back in late June, NASA revealed that sensors on its Curiosity rover were returning alarmingly high readings of methane that came seemingly out of nowhere. Determining where that methane came from — and whether the process responsible for it are geological or biological — is now a major area of research for scientists.

6 Days Ago   Figuring out how our reality took shape over billions of years is no easy task for scientists. Theories about how the Big Bang played out and the immediate aftermath are a dime a dozen, but researchers led by a team from the University of Arizona think they might stumble upon some of the secrets of galaxy formation by asking a supercomputer to simulate millions of virtual universes and seeing which ones come closest to what we see today.

6 Days Ago   The risks of being obese are fairly well documented, and while it's true that a person who is significantly overweight can better their odds of living longer with exercise, avoiding tobacco, and other healthy lifestyle choices, losing weight is oftentimes the best thing an obese person can do.

6 Days Ago   At the heart of our home galaxy is a supermassive black hole that gobbles up anything that gets too close. It's huge, with a mass of 4 million times that of our Sun, but size is a relative thing when we're talking about the universe, and astronomers just spotted a black hole in a distant galaxy that puts ours to shame.

6 Days Ago   We're in the midst of one of the best meteor showers of the year, but not everyone can stay up all night to watch the Perseids cascade across the night sky.

6 Days Ago   Like many galaxies, our own Milky Way is believed to revolve around a supermassive black hole. The location of the black hole, a feature known to astronomers as Sagittarius A* (pronounced "Sagittarius A star") isn't easily visible from Earth, but scientists can still catch a glimpse of it using infrared cameras during certain times of the year.
