Data from NASA's Juno Jupiter orbiter suggests that the Jovian moon Europa produces about 26 lb/s (12 kg/s) of oxygen or almost 100 times less than previously estimated. This changes the probability of life being found in the moon's subterranean ocean.

As spooky season wraps, NASA has a final Halloween treat. Using two X-ray telescopes, astronomers have visualized the ‘bones’ in one of space's most haunting phenomena, the pulsar wind nebula MSH 15-52, also known as the ‘cosmic hand' or 'hand of God'.

Able to detect gravitational waves and visible light sources, ESO's BlackGEM telescopic array at La Silla Observatory in Chile is on the hunt for ripples in space-time. And unlike existing observatories, it can pinpoint where they're coming from.

The James Webb Space Telescope is probing greater depths of space and time than other observatories. Now it's discovered galaxies with a structure like our own Milky Way 11 billion light-years away, challenging our understanding of galaxy formation.

Radio waves from Alaska have been transmitted to an asteroid passing just two lunar distances away from the Earth. The information gathered could arm scientists with information that may be critical in defending the planet from a collision some day.

When NASA's high-altitude balloon lifts off from Antarctica in December 2023 at the start of its up to four week voyage over the South Pole, it will carry one of the largest mirrors ever to fly on such a high-tech gas bag.

The James Webb Space Telescope has snapped its first in-focus image. With this milestone, the telescope is now set to meet or even exceed its original science goals. It was also recently spotted by another spacecraft in the area.

Fresh research has cast doubt on the theory that energetic outbursts from young stars blows away the cocoon of gas from which they formed, which in turn prevents them from growing any further.

NASA has released a collection of 50 stunning Hubble images to celebrate the veteran telescope’s 30th anniversary, which took place earlier this year. The images show 30 cosmic objects, visible to amateur astronomers across the globe.

NASA's James Webb Space Telescope has passed a major milestone, completing its prelaunch environmental testing after being subjected to weeks of acoustic and sine-vibration tests to determine whether it can withstand the rigors of a rocket launch.

The Hubble Space Telescope is celebrating its 30th launch anniversary with the release of a breathtakingly colorful portrait of star forming Nebulae - collectively nicknamed the "Cosmic Reef" - located in a galaxy orbiting the Milky Way.

The Spitzer Space Telescope was decommissioned on Jan. 30 this year, after more than 16 years in operation. Now NASA has released the observatory’s last-ever mosaic image, giving us a glimpse into how it works and revealing new features of a nebula.
