Astronomers spotted the most distant astronomical object ever

Amit Malewar

Shining only ~300 million years after the Big Bang, it may be home to the oldest stars in the universe.

First cloudless, Jupiter-like planet discovered

Amit Malewar

It completes a rotation around its star in just four-and-a-half days.

This image shows the disc around the young star AB Aurigae in polarized near-infrared light as seen with the European Very Large Telescope’s SPHERE instrument. Measurements of the molecular components of the disk at millimeter wavelengths reveal several unexpected properties including a warmer temperature, more dust, and a deficiency of sulfur

A schematic showing the motions of stars around the supermassive black hole in the center of our galaxy. The stars lie in an edge-on plane, and astronomers have used this constraint to deduce that the spin of the black hole must be less than about 0.1

The milky way could be spreading life from star to star

In 1871, Lord Kelvin suggested that life could propagate by traveling on meteorites. More than a century later, it was hypothesized that some achondrites were...

The distribution of satellite galaxies orbiting a computer-simulated galaxy, as predicted by the Lambda-cold-dark-matter cosmological model. The blue circles surround the brighter satellites, the white circles the ultrafaint satellites (so faint that they are not readily visible in the image). The ultrafaint satellites are amongst the most ancient galaxies in the Universe; they began to form when the Universe was only about 100 million years old (compared to its current age of 13.8 billion years). The image has been generated from simulations from the Auriga project carried out by researchers at the Institute for Computational Cosmology, Durham University, UK, the Heidelberg Institute for Theoretical Studies, Germany, and the Max Planck Institute for Astrophysics, Germany.'
