Planet The ESA’s Gaia mission mapped the positions and velocities of stars with extreme precision by measuring about one billion stars multiple times . It created a massive 3D map of the Milky Way that will pay scientific dividends for years to come . Gaia is based on
At first glance the large scale structure of the Universe may seem to be a swarming mass of unconnected galaxies. Yet somehow, they are! The ‘cosmic web’ is the largest scale structure of the Universe and consists of vast networks of interconnected filamentary structures that surround empty voids. A team of astronomers have used hundreds …

Foley UC Santa Cruz Posted on February 3, 2025 February 3, 2025 by Evan Gough The Hubble Space Telescope is a Powerful Science Instrument Despite its Age This Hubble image shows a supernova named SN 2022aajn in a distant galaxy about 600 million light-years away with the unwieldy name of WISEA J070815.11+210422.3. However , the obtuse yet scientifically descriptive names aren’t what’s important . What’s
It seems everyone is talking about the Moon and everyone wants to get their foot in the door with the renewed passion for lunar exploration. ESA too have jumped into the lunar landing game having just signed a contract with Thales Alenia Space to build its Argonaut Lunar Lander. Compared to other landers, it will …

When a star like the Sun dies, it puffs away its outer layers, leaving behind its glowing core. Without fusion to keep it heated, the white dwarf slowly cools down over billions of years. Astronomers have discovered that 6% of massive white dwarfs pause their cooling for up to 10 billion years, providing a stable habitable zone for any planets nearby. This gives life a long time to develop under extremely stable conditions.
