The Universe's Oldest Galaxies Could Be Right in the Milky Way's Backyard The Universe's Oldest Galaxies Could Be Right in the Milky Way's Backyard

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

This Exoplanet Is So Hot, It Apparently Tears Apart Water Molecules This Exoplanet Is So Hot, It Apparently Tears Apart Water Molecules

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 Kepler Space Telescope Not Dead Yet, May Even Have Another Exoplanet Survey Left in It NASA's Kepler Space Telescope Not Dead Yet, May Even Have Another Exoplanet Survey Left in It

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…

Congressional Committee Grills NASA and Northrop Grumman on James Webb Space Telescope Delays Congressional Committee Grills NASA and Northrop Grumman on James Webb Space Telescope Delays

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.

New Analysis of Potentially Habitable Exoplanet Makes Us Hungry for Better Telescopes  New Analysis of Potentially Habitable Exoplanet Makes Us Hungry for Better Telescopes 

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…

NASA Delays James Webb Space Telescope Yet Again, 'Commits' to a 2021 Launch NASA Delays James Webb Space Telescope Yet Again, 'Commits' to a 2021 Launch

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.

NASA Delays Flagship Space Telescope Mission Once Again NASA Delays Flagship Space Telescope Mission Once Again

Is this dang telescope ever going to launch?

Trump's Budget Would Scrap Top-Priority Telescope Trump's Budget Would Scrap Top-Priority Telescope

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

Next Generation Telescope Selects First Proposals From Scientific Community Next Generation Telescope Selects First Proposals From Scientific Community

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.

NASA Delays Hubble Successor Launch NASA Delays Hubble Successor Launch

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.

Behold the James Webb Telescope in all Its Unfurled Glory Behold the James Webb Telescope in all Its Unfurled Glory

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.

This Robotic Arm Slips James Webb's Mirrors Exactly Where They Need to Be This Robotic Arm Slips James Webb's Mirrors Exactly Where They Need to Be

We’re openly obsessed with the assembly of the segmented origami mirror for the James Webb Space Telescope. A gorgeous photo released today reveals the secret of an enormous robotic arm used to place the mirror segments to within a paper’s width of perfection.

You're Running Out of Time to Watch the First Origami Mirror Come Together You're Running Out of Time to Watch the First Origami Mirror Come Together

The James Webb Space Telescope construction team doesn’t waste time! After hitting the halfway-point in December, they’re now up to 12 of 18 mirrors installed. Check out the livestream from the cleanroom for building this fantastic telescope now, or forever hold your peace!

Aww Yeah, the James Webb Space Telescope Has Half Its Mirrors! Aww Yeah, the James Webb Space Telescope Has Half Its Mirrors!

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.

The James Webb Space Telescope's First Mirror Has Been Installed! The James Webb Space Telescope's First Mirror Has Been Installed!

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.

The James Webb Space Telescope Looks Like Gold Plated Space Origami The James Webb Space Telescope Looks Like Gold Plated Space Origami

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…

The Newly Proposed High Definition Space Telescope Makes Hubble Look Like a Toy The Newly Proposed High Definition Space Telescope Makes Hubble Look Like a Toy

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…

How We Keep 'New Telescope Smell' From Killing Space Telescopes How We Keep 'New Telescope Smell' From Killing Space Telescopes

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.

"Snow Cleaning" Keeps This Giant Telescope Mirror Perfectly Pristine "Snow Cleaning" Keeps This Giant Telescope Mirror Perfectly Pristine

The James Webb Space Telescope is the most powerful space telescope ever built, and its mirrors must be kept squeaky clean. Any debris, even tiny flecks of dust, could impact its science. Ergo, “snow cleaning:” the use of carbon dioxide snow to clean the mirrors thoroughly yet gently.

Dry Ice Is the Perfect Choice When You Have to Clean Your Space Mirror Dry Ice Is the Perfect Choice When You Have to Clean Your Space Mirror

Here are two engineers practicing “snow cleaning” on a test telescope mirror for the James Webb Space Telescope. I’m not exaggerating when I say this is the coolest way to dust off any surface without scratching it.
