The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The energy from the Sun is vital for life on Earth.

This image captures Comet Lemmon in dramatic fashion, its bright coma and faint tail arcing across the starfield.

Quantum gravity seeks to unify the theory of general relativity with quantum physics to describe how gravity works at very small scales. But there's a big puzzle surrounding the idea.

The X5.1-class eruption from sunspot AR4274 is this year's most powerful solar flare and Earth is in the firing line.

Lightweight, image stabilized and with 16x magnification, these Fujifilm binoculars are a must-have for outdoor stargazing.

Meet John McFall – Paralympian, medical doctor and member of ESA’s Astronaut Reserve. As part of ESA’s groundbreaking FLY initiative, John is helping prove that physical disability is no barrier to space. In this episode, he shares the results of a feasibility study showing no technical showstoppers for flying to the International Space Station with a prosthesis and talks about what’s next—from hardware certification and scientific proposals to astronaut reserve training and running in microgravity.

China's decision to delay the return of its Shenzhou 20 astronauts due to a possible space debris impact has led to discussion of space rescue planning — or lack of it.

SpaceX launched another big batch of its Starlink broadband satellites from Florida's Space Coast on Monday night (Nov. 10).

The James Webb Space Telescope (JWST) is the premier space science observatory designed to solve the mysteries of our solar system, look beyond to distant worlds around other stars, and probe the enigmatic structures and origins of our universe. As the successor to the Hubble Space Telescope, JWST is an international collaboration led by NASA with its partners, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

A new "exosuit" was put through its paces with analog astronauts in Australia. The research team would love to try the suit out on the International Space Station, too.

Galactic Energy's Ceres-1 rocket suffered a failure of its upper stage during a launch on Sunday (Nov. 9), leading to the loss of all three payloads on board.

Auroras may be visible from Alaska to Indiana as two incoming coronal mass ejections could spark geomagnetic storm conditions overnight.

New lab experiments suggest that water may not be a rare visitor delivered by chance but rather a fundamental ingredient woven into the process of planetary birth.
