Using NASA’s Wide-field Infrared Survey Explorer (WISE), astronomers have catalogued 20 previously undetected galaxies that are so bright they belong to an entirely new class of objects, including one that releases 10,000 times more energy than the Milky Way — even though it’s smaller. »
Chesley Bonestell was born long before the flight of the first airplane, and yet he’s well-known as the most influential people in aerospace art. The painter, designer and illustrator died the year of the Challenger disaster—1986—but not before witnessing humankind embrace space in much the way he’d dreamed. »
Located 1,500 light years away and measuring four light-years across, the gorgeous Medusa Nebula offers a sneak preview of what our Sun will look like when it finally enters into its final death throes.
In a remote stretch of the Pacific Ocean southeast of New Zealand, the broken remains of space stations and robotic freighters litter the ocean floor, four kilometers below the waves. The world’s space agencies call this region the South Pacific Ocean Uninhabited Area. But it’s also called the Spacecraft Cemetery. »
The list of countries that have mounted successful missions to Mars is not exactly long: the U.S. and Russia, as you’d expect, and more recently India. But now the United Arab Emirates has an ambitious plan to enter the race as soon as 2020. »
Spending more time in space requires the right tools for the job — and since these tools need to stand up outside the bounds of our own atmosphere, we have to make new tools.And of course, before they go up into space, they need to be tested. Here’s how — and where — they do it. »
Using the OSIRIS camera aboard the Rosetta spacecraft, ESA scientists have discovered a strange formation of what appears to be balancing boulders on comet 67P/Churyumov-Gerasimenko.
This week on Meanwhile in the Future, we ask what would happen if Earth had a second moon. How exactly that happens I won’t reveal — you’ll have to listen! But once it does, there are some really interesting things that we might notice on Earth, from tides and the night sky, to the potential destruction of Earth. »
Twenty years ago, discovering another Earth sounded like a science fictional dream. But within a generation, astronomers now believe we might do just that. »
Dwarf planets, comets, and asteroids are all the rage these days, but we shouldn’t neglect our Solar System’s outer gas planets and their moons. In this new NASA video, 70 days of Neptunian activity was compressed down to 34 seconds — and the effect is pretty damned cool. »
The icy white surface of Jupiter’s moon Europa is streaked in yellow-brown, cracks made by the ocean below. These dark streaks hint at the chemical composition of the ocean, which is one of the top places to search for alien life. Here’s encouraging news: The dark color may come from sea salt—the same stuff in our… »
You probably know that it takes about eight minutes for light travel from the surface of the Sun to our humble planet. But sunlight is far older than that—in fact, it’s thousands of years old. »
When NASA’s Orion crew module re-entered Earth’s atmosphere in 2014 tests, it did so covered in 180 small squares of an advanced heat-shielding material called Avcoat. Now, NASA’s research scientists are inspecting them to find out how they worked. Yes, that does appear to be a vacuum cleaner. »
We don’t fully know the answer. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and that extends that period of time. Let’s take a closer look. »
