The Dirty Afterlife of a Dead Satellite
Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people's lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century - satellite megaconstellations.
If the universe is expanding, how can galaxies collide?
You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome even the stretching of space itself

This Week's Sky at a Glance, February 6 – 15
The Winter Hexagon encompasses the brightest winter stars. Near Orion, the Big Dog prances and the Hare crouches. And the moonless dark this week opens telescopic deep-sky depths.

Sophie Adenot ready for first space mission
ESA astronaut Sophie Adenot is preparing to launch to the International Space Station for her first space mission: εpsilon.
After years of intensive training — from emergency procedures to spacewalk simulations — the countdown has begun. Flying alongside astronauts from NASA and Roscosmos, Sophie will join an international crew living and working together in space.
Aboard the ISS, Sophie will live and work in microgravity, conducting scientific research and performing a range of European- and French-led experiments that advance knowledge for life on Earth and in space.
Join us live on YouTube to watch the launch of Sophie Adenot.

The curious case of why methane spiked around Covid
With fewer cars on the road, planes in the air and factories running, the skies seemed cleaner during the Covid-19 pandemic. However, while there was a decline in pollutants such as nitrogen dioxide, scientists were surprised to see that methane surged in the early 2020s and then dropped – and now they know why.

The "Little Red Dots" Observed by Webb Were Direct-Collapse Black Holes
The discovery by JWST of a substantial population of compact "Little Red Dots" (LRDs) presented astronomers with a major mystery. By reproducing their spectra with simulations, a team argued that they were Direct Collapse Black Holes (DCBHs).
