Unlike the robotic explorers now prowling Mars’ dusty landscapes, these new craft -- launched by both NASA and a European-Russian collaboration -- will be engaged in a type of reconnaissance that hasn’t been tried since NASA’s Viking landers set down there in the mid-1970s. The new craft will go beyond merely scouting for locations that were once suitable for life. They’ll be on the hunt for life itself. Dead or alive.
More than six months after canceling what would have been the first spacewalk conducted by a team of two women, NASA has rescheduled the historic moment for Oct. 21. The spacewalk will be conducted by NASA astronauts Christina Koch, who has been living in space since March and was scheduled for the original all-women spacewalk, and Jessica Meir, who arrived at the International Space Station in September.
Since the availability of material is key to star formation in a galaxy, knowing the rate at which it is added and lost is important to understanding how galaxies evolve over time. And as Michael Foley of Astrobites summarized, characterizing the rates at which material is added to galaxies is crucial to understanding the details of this "galactic fountain" model.
Amazon CEO Jeff Bezos’ Blue Origin space venture has always shied away from saying how much it will cost to fly to the edge of the final frontier on its New Shepard suborbital spaceship. But today, Blue Origin CEO Bob Smith hinted at a ballpark figure.
It was just this year that we got our first real look at a black hole, and it matched many of the theoretical predictions that came before the Event Horizon Telescope (EHT) project made history. An impressive new NASA simulation shows us what that black hole might look like if we were closer.
GJ 3512 b is a gas giant orbiting a tiny red dwarf, GJ 3512. The planet itself is in an eccentric, 204-day orbit around its star, but spends most of its time closer to its parent than Mercury is to Sol. GJ 3512, however, can only manage ~0.2 percent of our Sun’s solar output. But a planet the size of GJ 3512 b isn’t supposed to exist.
NASA astronaut Christina Koch captured this incredible image from the International Space Station (ISS) yesterday. It shows a Russian Soyuz spacecraft making its way towards her, having launched from Baikonur Cosmodrome in Kazakhstan. “What it looks like from @Space_Station when your best friend achieves her lifelong dream to go to space,” Koch wrote on Twitter. “Caught the second stage in progress!”
It's a busy week at the International Space Station (ISS). With nine crewmembers currently on board, the orbiting laboratory will be unusually crowded until Thursday (Oct. 3), when three of those crewmembers are scheduled to return to Earth.
A rare trio of supermassive black holes has been caught in the act of coming together. Three of the light-gobbling monsters nuzzle shoulder to shoulder in SDSS J084905.51+111447.2, a system of three merging galaxies about 1 billion light-years from Earth, a new study reports.
The hellish planet Venus may have had a perfectly habitable environment for 2 to 3 billion years after the planet formed, suggesting life would have had ample time to emerge there, according to a new study.
