Metal-poor globular cluster forces astronomers to rethink theories

The discovery of the most metal-poor globular cluster recorded to date has forced scientists to rethink how both galaxies and globular clusters form.

Pluto’s snowcapped mountains are unlike any on Earth

A new study shows how methane snow accumulates on Pluto’s mountain peaks. These snowcaps – first seen by New Horizons in 2015 – look a lot like ones on Earth, but form in a very alien environment.

Astronomers identify 24 possible superhabitable worlds

Are there worlds out there – orbiting distant stars – even better suited for life than Earth? Might they be older, larger, warmer, wetter and with longer-living stars? Now astronomers have identified 24 possible superhabitable worlds.

Astronomers see a star ‘spaghettified’ by a black hole

Astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon – known as a tidal disruption event – is the closest such flare recorded to date at just over 215 million light-years from Earth.

James Webb Space Telescope passes environmental testing

The James Webb Space Telescope – successor to the Hubble – just passed a series of environmental testing trials, designed to simulate the rigors of its anticipated launch in 2021.

What is interstellar space?

You might be surprised to learn that interstellar space isn’t just vacuum. It’s full of gases, elements, and dust – very thinly spread, to be sure – but the building blocks of stars and planets.

Radar reveals 3 more subsurface polar lakes on Mars

Scientists with the European Space Agency say that the Mars Express orbiter has found evidence of three more salty lakes below Mars’ south pole. The discovery comes two years after the first lake was detected in 2018.
