LISA Construction Begins

Universe Today - Thu, 06/26/2025 - 7:23am

After years of research, and a completed pathfinder mission, the European Space Agency has officially begun the construction of the Laser Interferometer Space Antenna (LISA). This will consist of three spacecraft flying in formation, sending laser signals back and forth to detect passing gravitational waves - including previously undetected supermassive black hole mergers. ESA has chosen OHB System AG to construct the spacecraft, which are due to launch in 2035 on an Ariane 6 rocket.

The First Pictures from Vera Rubin are Here!

Universe Today - Thu, 06/26/2025 - 7:23am

I can recall the excitement of waiting for the first CCD Image I had taken to download, THAT was exciting. I was using a Starlight Express MX716 for those who can remember. This however is far more exciting. The Vera C. Rubin Observatory has officially come online and now we're looking at its first pictures. The telescope has completed ten hours of test observations, viewing millions of galaxies and Milky Way stars. It found thousands of new asteroids in just a few hours of observations, and took incredible pictures of the Triffid and Lagoon Nebulae. Over the course of its 10-year primary mission, it'll capture 800 images of every spot in the southern sky.

Satellite records expose fire driving Gran Chaco transformation

ESO Top News - Thu, 06/26/2025 - 4:30am

At ESA’s Living Planet Symposium, scientists have unveiled how the combination of different long-term, high-resolution satellite datasets from ESA’s Climate Change Initiative is shedding new light on the South American Gran Chaco – one of the world’s most endangered dry forest ecosystems. These data reveal, in remarkable clarity, that fire is the primary driver of widespread, accelerating deforestation across the region.
