Some 380 light years away in the constellation Scorpius lies a star that has puzzled astronomers for over 40 years. Called AR Scorpii, the star flashes brightly and fades again every couple minutes, like a lightbulb on a dimmer switch. Now, astronomers have identified the cause of the flickering, and it’s a reminder…
The astronomical map you see here doesn’t depict stars, it shows galaxies—1.2 million of them, to be exact, a new record for astronomers. This extraordinary new 3D scan of the universe provides yet more evidence that a mysterious substance known as dark energy is likely causing the universe to expand at an…
Space is not the soundless vacuum movies would have us believe. In fact, judging by these eerie recordings of the music being thrown off by the oldest stars in the Milky Way, space actually sounds like a bit of a party.
NASA’s Solar Dynamics Observatory just released a stunning video showing a pair of magnetic fields as they duel for supremacy on the surface of the sun.
How many nebulas do you think are in this photo? Careful, the answer is not quite what it seems.
It may not look much, but this fine filament of matter will soon blossom into something bright and spectacular, as its constituent gases begin to burn as a new set of stars.
Look deeply into this glowing red cloud drifting beyond the edges of our galaxy. Pretty weird, right? The weirdest thing of all, though, is what it’s been hiding.
Last week, we were blown away by a photograph from Mike Mezeul II depicting a storm over White Sands National Monument. We looked in a bit more on Mezeul’s portfolio and were amazed at what we saw.
Behold Trumpler 14, a dazzling star cluster located 8,000 light-years from Earth. Situated within the Carina Nebula, it’s home to one of the highest concentrations of massive, bright stars in the Milky Way. But as spectacular as these stellar objects appear be, their majestic appearance comes at a price.
As the world still mourns the passing of David Bowie, we can take some comfort that he’s posthumously received the most appropriate tribute ever: a constellation named after him, shaped in his iconic lightning bolt.
It may seem like some kind of delicate flower head, but you’re actually looking at the results of a computational model which is used to predict what happens inside a star when it spins quickly on its axis.
By studying a nearby sun-like star, astronomers have concluded that the Sun is capable of releasing solar flares a thousand times greater than anything previously recorded. Scientists say the chances of this are quite slim, but warn that such an event would threaten life on Earth.
Light pollution. It really screws up the view. It would be so great if the stars in the sky could still be seen over big metropolitan areas. But it doesn’t work like that. You have to go far away from civilization into deserts and nature to see the stars and cosmos the way they are meant to be seen. David Oliver Lennon
There’s a red dwarf about 35 light-years from here that’s spewing powerful, life crushing solar flares into space. These types of stellar objects are fairly common, leading to speculation that our galaxy is less habitable than we thought.
When the lights go out, everything we don’t see gets all that much more beautiful. Here are your photos of night.
A team of astronomers has discovered the most powerful aurora ever observed. But unlike our own Northern Lights, this astronomical phenomenon can be found 18 light years away in the skies above the brown dwarf LSR J1835+3259.
This latest image from the Hubble Space Telescope is utterly stunning: it’s of the Quintuplet Cluster, named for its five brightest stars. Up until 1990, we had no idea that this existed: because it’s so close to the center of the galaxy, dust has blocked our view of it.
Recent headlines are warning that the Earth will enter into a “mini ice age” in about 20 years because the sun is heading towards a period of very low output. Here’s why this scenario is extremely unlikely.
Scientists at the Open University, UK, have discovered a rare group of five gravitationally bound stars they say should “put the makers of Star Wars to shame.”
Here’s a really cool visualization from astronomer Scott Manley that shows what our sky might look like if we could actually see all the asteroids. Asteroids aren’t visible to the naked eye because they’re too small to register but Manley was able to reveal the known asteroids and speed them up to exaggerate how they…
