Astronomers have witnessed one of the most dramatic "switching on" events ever seen as a distant supermassive black hole began greedily feasting on its surrounding matter.

Europe's Ariane 5 heavy-lift vehicle is now officially retired, and the rocket's final launch on July 5 was picture-perfect.

How would astronauts walk on an asteroid? With the potential to sink into killer "ball pits" or to take jumps that launch them into space, the answer is "carefully."

A wormhole, in the context of theoretical physics and general relativity, is a hypothetical passage or tunnel that connects two separate points in spacetime. It is often depicted as a shortcut or a bridge between distant locations, allowing for rapid travel or even potential connections between different universes or dimensions. Here are some key points about wormholes:

Valerie Weiss chats about her acclaimed 'Strange New Worlds' episode for Season 2.

The James Webb Space Telescope has detected the most distant active supermassive black hole to date, and researchers aren't sure how it could have formed so early in the universe's history.

July's full Buck Moon — the first of four consecutive supermoons — rose on July 3, and an astronaut aboard the ISS snapped a stunning view of the celestial sight.

Exponential growth in Starlink orbital collision avoidance maneuvers in the past six months is sparking concerns over the long-term sustainability of satellite operations.

Hum from onboard electronics that power SpaceX's internet-beaming Starlink satellites may disturb radio astronomy observations, a new study has found.

The intrepid infrared explorer is offering astronomers a jump back in time, enabling them to see quasars at earlier times than ever before.

Sally Ride now stands tall on the grounds of the Ronald Reagan Presidential Library and Museum in California, where a statue of her was unveiled as part of an Independence Day celebration.

India stacked its Chandrayaan 3 moon lander and rover atop their rocket ride on Wednesday (July 5), notching a big milestone ahead of the mission's planned July 13 launch.

In this week's episode of 'Star Trek: Strange New Worlds,' not only is there a throwback to the original series pilot, but Lt. Erica Ortegas has her chance to shine.

Earth reaches the farthest point in its orbit around the sun for 2023, called aphelion, on Thursday (July 6) at a distance of 94,506,364 miles (152,093,250 km).

Europe’s venerable Ariane 5 rocket blasted off on its 117th and final flight Wednesday, successfully boosting two communications satellites into orbit but leaving the European space program without a large satellite launcher of its own until a delayed successor comes on line.

Over the 14 years since its launch, the Lunar Reconnaissance Orbiter has produced images and data proven that have transformed our understanding of the moon. But how much longer can the orbiter last?

Ariane 6 may launch later this year to provide fresh European access to space, but it faces stiff competition from veteran US competitor SpaceX.

Last week, members of ESA’s astronaut support teams participated in a helicopter underwater escape training. This training is mandatory for people involved in astronaut landing operations, including flight surgeons and photographers, who capture the key moments of an astronaut mission.

When the RIME antenna on ESA’s Juice mission failed to deploy a few days after launch, the engineering teams faced the mighty challenge to understand the fault and rectify it. At stake was a chance to see inside Jupiter’s mysterious icy moons.
