It has taken over ten years, but astronomers have finally won a prolonged game of cosmic hide-and-seek with a planet hiding around the star Beta Pictoris.

Astronomers using NASA’s James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in our Milky Way galaxy. The young, nearby star Beta Pictoris was already known to h

Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported in a paper submitted to the arXiv preprint server o

A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the lightest exoplanets ever imaged from the ground. After s

European astronomers have conducted optical and radio observations of an enigmatic radio source designated GRS 0917+75. As a result, they found that GRS 0917+75 is a giant radio galaxy and determined its properties. The new findings were published July 3 on the preprint server ar

Think of quasars as time machines. Rare but revealing. They are light from the beginnings of the universe that let astronomers investigate how early galaxies formed.

Astronomers have recently started looking for black holes bigger than galaxies. Brian Lacki explains how these “stupendously large black holes” might be used by alien civilisations, and what makes them such an intriguing possibility

Terzan 5 is a globular cluster with some unusual properties that have led a team of astronomers to suspect that it is more than meets the eye.

The expansion of the universe is still accelerating under the influence of dark energy, despite recent claims to the contrary averting a cosmological crisis, according to new research.

Astronomers using NASA’s Hubble Space Telescope have found something they never expected — ultraviolet light from a galaxy that existed just 1.4 billion years after the big bang.

A new exoplanet model screens rocky worlds by their ability to retain atmospheres over geologic timescales, helping narrow the search for potentially habitable planets beyond Earth.

A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA’s Nancy Grace Roman Space Telescope, launching later this summer. This sneak peek gives astronomers
