The biggest-ever study of astronaut health gives us clues on what to look for in future long-haul space missions.

The findings could shed light on dark matter and dark energy

Astronomers have discovered a cold brown dwarf – otherwise known as a “super planet” – for the first time using a radio telescope. Brown dwarfs are vast, sized between 15 and 75 times the mass of Jupiter, and have gaseous atmospheres similar to some of the planets in our solar system. They are also often known as “failed stars” because of the way that they shine.

SpaceX looks ready to proceed to the next crucial phase of its Starship spacecraft development program: A 15km (50,000 feet) test flight.

Lab experiments developing and testing fake Martian dirt are proving just how difficult it would be to farm on the Red Planet.

Researchers tapped by NASA just conducted a first test of a decades-old concept.

A team of architects in Japan, under the “Space Port Japan Association”, have designed a breathtaking concept for a futuristic, 4-story spaceport city. The spaceport rises from an island that floats in Tokyo Bay, with the skyscrapers of Japan’s capital in the background. It is designed to launch tourists on day trips to space, where they will be able to see the building’s huge roof as well as — glimpse the curvature of the Earth & experience zero gravity.

The Sentinel-6 Michael Freilich satellite is set to launch on Saturday as the next generation of spacecraft keeping an eye on global sea level. The satellite will launch from Vandenberg Air Force Base in California on November 21 at 12:17 p.m. ET.

The Big Ear Radio Telescope in Delaware, Ohio, was disassembled in 1998 having operated for over 30 years. It was replaced by a golf course. Big Ear was never the world’s biggest radio telescope, nor its most sensitive. But Big Ear nevertheless made one of the most famous observations in the history of astronomy, one that till this day has never been explained.

NASA plans to launch a satellite tomorrow that will follow the effects of climate change on the world’s oceans and gather data to improve weather forecasts. The satellite will continue NASA’s three decades-long work to document rising sea levels and will give scientists a more precise view of the coastlines than they’ve ever had from space.

A "fossil galaxy" has been found hidden inside of our Milky Way. The discovery of the long-dead galaxy could change our understanding of the history of the Milky Way, and how it became the vast web of stars that surrounds us today. The fossil, known as Heracles, is thought to have collided with the Milky Way 10 billion years ago, when our galaxy was still at a very young age.

National Science Foundation decides to decommission iconic radio observatory

The iconic Arecibo radio telescope in Puerto Rico is to be dismantled, officials announce.

According to SpaceX CEO Elon Musk, the first human colony on the Martian surface needs to be built using "glass domes"

NASA has some truly amazing photos of Jupiter that almost look like Van Gogh paintings.

This could be huge. It also could be nothing.

NASA plans to build a nuclear power plant on the moon and Mars to support its long-term exploration plans.

A study published in the journal Astrobiology identified two dozen planets with conditions which may be more suitable for life than those on Earth, including worlds that are older, larger, slightly warmer and possibly wetter, RT reported. Some of the “superhabitable” other worlds also orbit stars that are friendlier to life than our sun, because they change more slowly and have longer lifespans.

We're building a Great Garbage Shell around the Earth, full of defunct satellites and tiny pieces of junk.

Not thought to be volcanically active, Mars may have experienced an eruption just 53,000 years ago.
