Blast from the Past

Astronomers have discovered that CK Vulpeculae, first seen as a bright new star in 1670, is approximately five times farther away than previously thought. This makes the 1670 explosion of CK ...

Galaxy Encounter Violently Disturbed Milky Way

The long-held belief that the Milky Way, the galaxy containing Earth and the solar system, is relatively static has been ruptured by fresh cosmic insight. The spiral-shaped disc of stars and planets ...

Milky Way Family Tree

Galaxies formed by the merging of smaller progenitor galaxies. An international team of astrophysicists has succeeded in reconstructing the merger history of our home galaxy, creating a complete ...

Scientists Make Sound-Waves from a Quantum Vacuum at the Black Hole Laboratory

Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behaviour of black ...

Newborn Jets in Distant Galaxies

Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered 'engines' at the cores of some distant galaxies have launched new, superfast jets of ...

Blue Ring Nebula: 16-Year-Old Cosmic Mystery Solved, Revealing Stellar Missing Link

Astronomers have solved the 16-year-old mystery surrounding the Blue Ring Nebula - an unusual, large, faint blob of gas with a star at its center. This object is unlike any they'd ever seen ...

Cosmic Flashes Come in All Different Sizes

By studying the site of a spectacular stellar explosion seen in April 2020, scientists have used four European radio telescopes to confirm that astronomy's most exciting puzzle is about to be ...

Building Blocks of Life Can Form Long Before Stars

An international team of scientists have shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in ...

Understanding Astrophysics With Laser-Accelerated Protons

Bringing huge amounts of protons up to speed in the shortest distance in fractions of a second -- that's what laser acceleration technology, greatly improved in recent years, can do. An ...

History of Temperature Changes in the Universe Revealed

How hot is the Universe today? How hot was it before? A new study by an international team of researchers suggests that the mean temperature of gas in large structures of the Universe has increased ...

Birth of Magnetar from Colossal Collision Potentially Spotted for First Time

Researchers spotted a short gamma ray burst 10 times brighter than predicted. The mysterious brightness might signal the birth of a rare magnetar, formed from two neutron stars merging, which has ...

Advanced Atomic Clock Makes a Better Dark Matter Detector

Researchers have used a state-of-the-art atomic clock to narrow the search for elusive dark matter, an example of how continual improvements in clocks have value beyond ...

Massive explosions of energy happening thousands of light-years from Earth may have left traces in our planet's biology and geology, according to new ...

Dark Matter from the Depths of the Universe

Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected forms. Exotic low-mass fields (ELFs), for example, could propagate through space and cause feeble ...

Radioactive Elements May Be Crucial to the Habitability of Rocky Planets

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from ...

Black Hole or No Black Hole: On the Outcome of Neutron Star Collisions

A new study investigates black-hole formation in neutron star mergers. Computer simulations show that the properties of dense nuclear matter play a crucial role, which directly links the ...

The Universe Is Getting Hot, Hot, Hot, a New Study Suggests

The universe is getting hotter, a new study has found. The study probed the thermal history of the universe over the last 10 billion years. It found that the mean temperature of gas across the ...

Stellar Flares Can Lead to Diminishment of a Planet's Habitability

Researchers identified which stars were most likely to host habitable exoplanets based on the calculated erosion rates of the planetary ...

Final Dance of Unequal Black Hole Partners

Researchers used the Frontera supercomputer to model for the first time a black hole merger of two black holes with very different sizes (128:1). The research required seven months of constant ...

Has the Hidden Matter of the Universe Been Discovered?

Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, ...
