One of the biggest challenges in astrophysics is accurately determining the ages of stars. This is because once a star has begun steady nuclear fusion on the main sequence, it varies by very little for billions of years.

A recent study has reported that 1 in 12 pairs of stars may have engulfed a planet, aiding our understanding in the well-known ‘three-body problem’.

Cosmological models are largely settled on the structure of the very early universe which, moments after the big bang, could be modelled as a smooth, homogeneous fluid.

Our judges, Adam Block, Alex Curry, Nik Szymanek and Mustafa Aydın, chose the winners of the February 2024 contests.

Two teams have studied the extremely bright and young galaxy GN-z11, existing when the universe was only around 430 million years old.

Have you ever wondered what it takes to capture the inspiring beauty of a solar eclipse? Or perhaps you've attempted to photograph one yourself and are looking to refine your skills. 

We are thrilled to announce an exclusive webinar that promises to redefine your approach to narrowband image processing.

Dear Telescope Live Community,

There are three primary techniques for studying binary star systems. The first technique, direct imaging, allows astronomers to visually resolve both stars in the binary system when they are sufficiently separated.

Earth's geology is uniquely characterised, within the solar system, by its layered differentiation and active plate tectonics, facilitating ongoing crustal recycling.

A team of researchers at the Smithsonian Astrophysical Observatory part of the centre for Astrophysics | Harvard & Smithsonian have detected an extremely powerful eruption from a young star.

Theories about the first black holes suggest they formed shortly after the Big Bang, either as "heavy seeds" born from the direct collapse of massive gas clouds or as smaller "light seeds" from the remnants of early stars
