As civilisations become more and more advanced, their power needs also increase. It’s likely that an advanced civilisation might need so much power that they enclose their host star in solar energy collecting satellites. These Dyson Swarms will trap heat so any planets within the sphere are likely to experience a temperature increase. A new …

We know that regular supernovae pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and little bit harder to spot.This post was originally published on this site
Dark Energy is a mystery so daunting that it stretches and strains our most robust theories. The Universe is expanding, driven by the unknown force that we’ve named Dark Energy. Dark Energy is also accelerating the rate of expansion. If scientists could figure out why, it would open up a whole new avenue of understanding.This …

The ESA’s Euclid Space Telescope has already wowed us with some fantastic images. After launching in July 2023, the telescope delivered some stunning first images of the Perseus Cluster, the Horsehead Nebula, and other astronomical objects. Now, the telescope has released its first images of its three Deep Fields.This post was originally published on this …

The James Webb Space Telescope (JWST) has achieved groundbreaking discoveries in the field of exoplanet studies. In particular, it has made strides in the analysis of their atmospheres by studying light from the parent star as it travels through the gas surrounding the planets. JWST has recently bucked the trend and observed a some gas …

After an unexpectedly long mission in orbit, astronauts Suni Williams and Butch Wilmore finally arrived home. Their SpaceX Dragon capsule detached from the International Space Station early Tuesday morning, beginning the de-orbiting process. Nick Hague and Aleksandr Gorbunov are also on board and, following a nail biting descent, finally at 7.58pm EDT today.This post was …

The most dangerous parts of a supernova explosion are the outputs like X-rays and gamma rays. Even though they only share a small fraction of a supernova’s power, they are extremely dangerous.This post was originally published on this site
The Square Kilometre Array (SKA) remains under construction with completion still a few years away. However, engineers recently provided an exciting preview having installed 1,024 of the planned 131,072 antennas and capturing a test image of the sky. The image covers about 25 square degrees and reveals 85 of the brightest known galaxies in the …
