The Universe’s earliest epochs appear to be written into the small dwarf galaxies orbiting our own galactic home, the Milky Way.

There’s an exoplanet whose surface is so hot, it rips apart water molecules. It’s almost a star, but not quite; it’s an ultra-hot, Jupiter-like world located around 880 light-years from Earth.

NASA’s $600 million Kepler space telescope, which is more or less running on thruster fuel fumes nearly a decade after its launch in 2009, woke up from a four-week hibernation phase on Thursday and is transmitting data back to Earth, Space.com reported on Friday. If all goes well, it may even be capable of continuing…

The House Committee on Science, Space, and Technology has concluded two days of hearings focused on trying to understand how the James Webb Space Telescope—NASA’s flagship telescope project—could have gone from a 2007 planned launch with a $500 million budget to a 2021 launch with a $9.6 billion budget.

Eleven light-years from Earth, orbiting a dim red star, there’s an exoplanet called Ross 128b that, as we recently reported, has some the best prospects for life of any known distant world. New results may help astronomers figure out what the planet is made of—and they offer more evidence that it might be inside its…

Following an independent review, NASA’s planned James Webb Space Telescope has received yet another delay in its mission schedule. This time, NASA has moved the target launch from May 2020 to March 2021.

Is this dang telescope ever going to launch?

President Donald Trump’s 2019 budget request would nix the Wide Field Infrared Survey Telescope (WFIRST), and scientists aren’t happy.

There’ve been some incredible images of the James Webb Space Telescope, the next generation telescope and successor to the Hubble. But we’re not really here to look at images of telescopes. We’re here to learn some dope space stuff.

The Hubble Space Telescope is incredible and has done some truly remarkable science, but it’s getting old. After all, it was launched in 1990. Taking its place is the James Webb Space Telescope, an $8 billion-plus experiment that was scheduled to launch in October 2018.

Like a dandelion reaching up to the sky on a warm spring day, the James Webb Telescope peers upwards in this stunning new photo released today by NASA. Still under construction, the powerful space-bound telescope will soon be shipped across the country for the next phase of its development.

What better way to spend the holidays than watching NASA technicians scurry around assembling mirror segments on the James Webb Space Telescope? With the 9th of 18 segments installed last week, we’re that much closer to hunting for signs of life on alien worlds and making our universe a little less lonely.

NASA has announced that they’ve installed the first of the James Webb Space Telescope’s mirrors. The part is one of eighteen that will eventually be bolted to the satellite, which is set to launch in 2018.

Like new cars, new telescopes come with their own unique smell. Unlike cars, telescopes are delicate enough that this smell can damage the high-precision instruments, killing them with their own outgassing. Here’s how NASA protects fragile space telescopes from themselves.
