The James Webb Space Telescope's Orbit

It's the "largest and most technically complex space science telescope NASA has ever built."

NASA's James Webb Space Telescope completes its final tests

Better Late Than Never

NASA's James Webb Space Telescope may finally launch in 2021 after having completed its final litany of critical software and electrical systems tests.

NASA’s James Webb Space Telescope Completes Its Final Tests

After decades of development, will NASA's largest space telescope finally get off the ground?

Massive space telescopes might have their own CubeSat fleets.

Tiny satellites could be "guide stars" for massive space telescopes

Off World

A new study describes a system which would use a second satellite like a laser light pointer to help large space telescopes lock on to distant objects. 

Tiny Satellites Could Be “Guide Stars” for Massive Space Telescopes

CubeSats with lasers could guide our gaze into the cosmos.

NASA wants to ensure the James Webb is in perfect condition before it's sent a million miles away, so far we can't fix it.

The James Webb telescope is delayed. Again. Here are 4 things to know about it

The James Webb Space Telescope is now slated to launch in May 2020, two years later than originally planned. Here's why, and the impact it may have.

The James Webb Telescope Is Delayed. Again. Here Are 4 Things to Know About it

NASA officials say the delay is about "getting it right." 

This is the most ambitious telescope international space agencies have attempted.

Technical, budget problems will delay the James Webb Telescope again

If technical issues continue to delay the James Webb Space Telescope, the project could exceed Congress' budget cap, leaving its future uncertain.

Technical, Budget Problems Will Delay the James Webb Telescope Again

“It took longer than predicted, but it’s about getting it right." 

It's another landmark observation in the next-gen of astronomy.

These are real images of a star going supernova

Astronomers used the Optical Gravitational Lensing Experiment (OGLE) to capture, in great detail, a star going supernova in slow motion.

This star exploded in a truly unique way.

Scientists are eager to take advantage of the powerful device.

A telescope 100X stronger than Hubble will unveil parts of the cosmos we've never seen

NASA has announced the selection of 13 research programs that will comprise the Early Release period for the James Webb Space Telescope (JWST).

A Telescope 100X Stronger Than Hubble Will Unveil Parts of the Cosmos We've Never Seen

"We fully expect to be surprised by what we find."

A Telescope 100X Stronger Than Hubble Will Unveil Parts of the Cosmos We’ve Never Seen

Dark energy might not be what we thought.

Astronomers have uncovered evidence of "dynamical dark energy"

Dark matter and dark energy are two of the greatest mysteries in the cosmos.

Astronomers Have Uncovered Evidence of “Dynamical Dark Energy”

The mysterious energy that drives the expansion of the universe may not be a constant. 

Don't worry, there's nothing wrong with the telescope.
