It's not how big your laser is, it's how you use it: space law is an important part of the fight against space debris

Space is getting crowded. More than 100 million tiny pieces of debris are spinning in Earth orbit, along with tens of thousands of bigger chunks and around 3,300 functioning satellites.

Large satellite constellations such as Starlink are becoming more common, infuriating astronomers and baffling casual skywatchers. In the coming decade, we may see many more satellites launched than in all of history up to now.

Collisions between objects in orbit are getting harder to avoid. Several technologies for getting out of harm's way have been proposed, most recently the plan from Australian company Electro Optic Systems (EOS) to use a pair of ground-based lasers to track and "nudge" it away from potential collisions or even out of orbit altogether.

Tools like this will be in high demand in coming years. But alongside new technology, we also need to work out the best ways to regulate activity in and decide who is responsible for what.

Active debris removal

EOS's laser system is just one of a host of "active debris removal" (ADR) technologies proposed over the past decade.

One of the most comprehensive pictures of our changing planet is now available to the public. Thanks to the close collaboration between Google Earth, ESA, the European Commission, NASA and the US Geological Survey, 24 million satellite photos from the past 37 years have been embedded into a new layer of Google Earth – creating a new, explorable view of time on our planet.

Galileo sunspot sketches versus modern ‘deep learning’ AI

It's a fascinating thought to consider.

What exactly did the Sun look like, centuries ago? What would we see, if astronomers back in the time of Kepler and Galileo had monitoring the Sun across the , available to them?

Thanks to modern artificial intelligence, there may be a way to actually 'see' just what state the Sun was in, way back in those days of yore. A recent study, titled "Generation of Modern Satellite Data from Galileo Sunspot Drawings in 1612 by Deep Learning" out February 2021 in the Astrophysical Journal of the American Astronomical Society used an innovative set of deductions to compare sketches of sunspots with modern views from ground and space-based observations. The study was led by Harim Lee from Kyung Hee University in the Republic of South Korea.

Galileo and the Sun

Sunspot records represent one of the longest sets of astronomical data available, going all the way back to Chinese observations in 1128 A.D.

WASHINGTON — SpaceX has added more than $300 million to a fundraising round announced earlier this year to support continued work on its Starship launch system and Starlink satellite constellation.

In an amended filing with the U.S. Securities and Exchange Commission April 14, the company revised a filing in February that disclosed raising $850 million.

In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which a lifeless rocky planet around a sun-like star could evolve to have oxygen in its atmosphere. The new findings, published April 13 in AGU Advances, highli

Jeff Bezos' Blue Origin launched Wednesday from Texas what may be the last test flight for its New Shepard rocket before it carries people later this year. The rocket lifted off about 12:50 p.m. EDT from the company's spaceport near Van Horn, about 120 miles southeast of El Paso. New Shepard soared into the hazy spring sky, reaching velocity of more than 2,200 mph. "Now the antic

With NASA's Space Shuttle program gone for nearly a decade, a slew of private firms have stepped up their efforts to provide manned space flight capabilities, not just for US governmental needs, but also for space tourism. In a Wednesday test described by the company as an "astronaut rehearsal," Blue Origin successfully blasted a New Shepard rocket into suborbital space and then landed the

In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told. Data from 19 observatories are being released that promise to give unparalleled insight into this black hole and the system it powers, and to improve tests of Einstein's The
