Six hundred million light years away, a pair of black holes spiral furiously about one another at the brilliant core of a starburst galaxy. »
Earth is the only planet in our Solar System where life is known to exist. Note the use of the word “known,” which indicates that our knowledge of the Solar System is still in its infancy, and the search for life continues. However, from all observable indications, Earth is the only place in our Solar System where… »
Deep space is a wonderland of strange and awe-inspiring sights, but few astronomical curiosities match the exquisite beauty of the Twin Jet Nebula, a dying, binary star that looks like a pair of iridescent butterfly wings. »
When it launches in October 2018, the James Webb Space Telescope will become the largest optical telescope in space. With its 6.5 meter wide mirror, it will gather infrared light from up to 13.5 billion light years away, giving astronomers a look at the earliest moments of the universe. But the mirror is too big to… »
We all know that major storms can wreak havoc, flooding cities and decimating infrastructure. But there’s an even bigger worry than wind and rain: space weather. If a massive solar storm hit us, our technology would be wiped out. The entire planet could go dark. »
A new theory proposes that Saturn’s outermost ring formed in the wake of an ancient collision between two icy satellites, and that similar collisions may account for comparable ringed structures around other planets. »
Forgive this barred spiral galaxy if it looks a little messy. It’s the survivor of a galactic collision that bent and twisted the galaxy’s original shape, according to astronomers. »
The James Webb Space Telescope (JWST), which will be “in many ways a hundred times” more capable than Hubble, isn’t launching until 2018, but already astrophysicists are thinking about its successor. They’re calling it the High Definition Space Telescope (HDST). That’s it on the far right, towering over both its… »
Using data collected by NASA’s New Horizons spacecraft, Icelandic imaging wizard Björn Jónsson has produced a stunning animated visualization of the now historic Pluto flyby. »
Naming a planet used to be an honor reserved for the astronomer who discovered it, but these days, we’re finding too many to keep up. Now, the International Astronomical Union has opened the sacred process up to the internet, bless their brave souls. »
Behold the lightest planet ever imaged by a telescope: an extremely young, Jovian-like planet that’s twice the size of Jupiter. Astronomers detected it through visible light, which is an extraordinary feat for a planet of this nature.
Brace yourselves: winter is coming. And by winter I mean the slow heat-death of the Universe, and by brace yourselves I mean don’t get terribly concerned because the process will take a very, very, very long time. (But still, it’s coming.) »
It’s generally assumed that we will eventually find signs of life in the galaxy. But rarely do we consider searching for advanced civilizations that have destroyed themselves. Here’s how we could do it—and what the search for dead aliens could tell us about our own future. »
A multi-decade analysis of a distant pulsar is affirming the longstanding notion that the gravitational constant—one of four fundamental forces of nature—is the same everywhere in the universe. »
This gorgeous filtered image is a 6,000-year-old snapshot of a slowly dying star. When the star at the center of the Little Gem Nebula reached the end of its lifespan, it began ejecting its outer layers into space in glowing clouds of gas. Its stellar wind pushes the gas outward into this colorful bubble.
The Moon may be Earth’s kid brother, but Saturn’s moons seem more gnats on an elephant in this incredible image captured by the Cassini probe. »
Most of us will never set foot on Mars, but thanks to NASA’s unceasing public outreach campaign, now we can all imagine what that might be like. To commemorate the three year anniversary of the Curiosity rover’s Martian landing, NASA has unveiled two new web tools that allow you to explore the Red Planet’s surface and… »
Calculations made by a JPL-California research scientist suggest that thin strands of dark matter filaments are spreading out from large planetary bodies like Earth and Jupiter. If true, it’s a possible sign that we may be able to finally detect these hypothetical forms of matter. »
Europe’s MSG-4 geostationary weather satellite is up and running after its launch on July 15. Earlier today, it’s Spinning Enhanced Visible Infrared Imager (SEVIRI) snapped its first image of Earth. And yes, we are impressed.
