Magnetic Chamber can Simulate Microgravity (or Mars Gravity) Here on Earth
There are plenty of processes that might be easier in lower gravity. So far, the biggest hindrance to developing those processes has been the expense of launching equipment to the low gravity environments of the ISS or other space-based research stations. Testing on the ground would be preferable both for ease of use and much lower cost, but the Earth’s gravity usually puts a stop to that. Some scientists see another way. Using magnetic fields can artificially simulate a zero-gravity environment, and now a team from Florida State University’s (FSU’s) National High Magnetic Field Laboratory has developed a system that can hold a much larger sample than previous iterations.
China launches military satellites into orbit after delay
China sent new military satellites to orbit Wednesday (Nov. 3) for an undisclosed mission, following a lengthy launch delay.
NASA is Getting Serious About the Search for Life in the Universe
Frameworks are a valuable tool in science. They give context to sometimes abstract concepts such as “how powerful can an alien civilization be” (Kardashev scale) or “how developed is this technology?” (Technology Readiness Levels). Now, NASA has developed a new scale to help give context to what some consider one of the agency’s most critical missions – the search for extraterrestrial life.

Glaciers across the globe have lost over nine trillion tonnes of ice in half a century. How will glaciers look over the coming decades? “It all depends on what humans are doing now in terms of greenhouse gas emissions:” this is the message one scientist delivered during an ESA-led expedition to the Gorner Glacier in Switzerland – one of the biggest ice masses in the Alps.
Solar storm from 'cannibal' sun eruption may impact power grid and bring auroras as far south as Pennsylvania
A powerful solar storm could interfere with power grids, satellites and radio signals — although it might also have sent the beautiful northern lights incredibly far south.

Mining the moon's water will require a massive infrastructure investment, but should we do it?
We live in a world in which momentous decisions are made by people often without forethought.
Enormous 'shipyard' of ancient galaxies discovered 11 billion light-years away
Astronomers have confirmed the existence of a massive protocluster 11 billion light-years away that acts as an assembly yard for over 60 emerging galaxies.
China's hypersonic weapon test no cause for panic, experts say
China's mysterious recent space-tech test is not a sign that the sky is falling.

ESA astronaut Thomas Pesquet had a call with the French President Emmanuel Macron on 4 November 2021 from the International Space Station. The call came at the end of Thomas’s second mission to space called Alpha.
Explore ESA’s interactive Climate Change Kit
Arguably, humankind has never been more aware of the jeopardy we and the planet face because of climate change. As world leaders at COP26 work to accelerate action towards reducing greenhouse gas emissions to keep the goal of 1.5°C temperature rise within reach, we bring you a new easy-to-use guide on what ESA is doing to understand and monitor climate change from space – data that are essential for policy-makers.
What’s Snuffing Out Galaxies Before Their Time?
In the Milky Way, the formation rate of stars is about one solar mass every year. About 10 billion years ago, it was ten solar masses every year. What happened?

Astronomers Might Have Found a Planet in Another Galaxy
Not that long ago,, astronomers weren’t sure that exoplanets even existed. Now we know that there are thousands of them and that most stars probably harbour exoplanets. There could be hundreds of billions of exoplanets in the Milky Way, by some estimates. So there’s no reason to think that stars in other galaxies don’t host planets.
