Black hole ripples could help pin down expansion of universe

The echoes of light from jets launched from black holes offers a new way to pin down the distance to these exotic objects and to study a largely unobserved population in the center of the Galaxy. It could also even help determine ...

PIGS find ancient stars in the heart of the Milky Way

An international team of researchers has obtained the largest set of detailed observations yet of the oldest stars in the center of our Galaxy, the Milky Way. The Pristine Inner Galaxy Survey (PIGS) team finds that this group ...

Astronomers witness energetic switch on of black hole

A team of astronomers led by researchers from the University of Birmingham, University College London and Queen's University Belfast have discovered one of the most dramatic 'switches on' of a black hole ever seen. They will ...

'Sandwich' discovery offers new explanation for planet formation

Scientists have made a new discovery on how small planets might form. Researchers at the University of Warwick investigated the "birth environment" of planets—areas of gas and dust that swirl around a central star—known ...

Solar astronomers discover 'shooting stars' on the sun's corona

A team of astronomers from several European institutions led by Northumbria University in Newcastle has discovered "shooting stars" on the sun. Observations from the European Space Agency's Solar Orbiter (SolO) have revealed ...

Evidence of the amino acid tryptophan found in space

Using data from the Spitzer space observatory, Dr. Susana Iglesias-Groth, a researcher from The Instituto de Astrofísica de Canarias (IAC), has found evidence for the existence of the amino acid tryptophan in the interstellar ...

An X-ray look at the heart of powerful quasars

Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner ...

Redness of Neptunian asteroids sheds light on early solar system

Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red color, implying the existence of two populations of asteroids in the region, according to a new study by an international ...
