New Results Show Dark Energy May Vary Over Time
A new study using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton suggests that dark energy may have varied over cosmic time. This artist’s…
New Research Solves Key Mystery in the Birth of Massive Black Holes
When the universe was still a baby – less than 1 billion years old – some of its stars turned into monster black holes. A…
New Simulations Provide Clues on How to Escape a Black Hole
Black holes are known for their voracious appetites, binging on matter with such ferocity that not even light can escape once it’s swallowed up. Less…
Breakthrough Allows Astronomers To See What Makes Sagittarius A* Glow
A black hole four million times as massive as our Sun lurks at the center of the Milky Way. This black hole, called Sagittarius A*…
Astronomers Explain Mystery Orbits in Outermost Reaches of Solar System
The strange orbits of some objects in the farthest reaches of our solar system, hypothesised by some astronomers to be shaped by an unknown ninth…
Hypernova Observations Reveal the Death of the Massive Stars
The end of a star’s life can occur in a tranquil manner in the case of low mass stars, such as the Sun. This is…
Scientists Reveal Orderly Chaos of Black Holes
An international consortium of scientists studying gamma-ray bursts (GRBs) as part of the POLAR (GRB polarimeter) experiment has revealed that high-energy photon emissions from black…
Astronomers Reveal New Way Supermassive Black Holes Are “Fed”
Supermassive black holes weigh millions to billions times more than our sun and lie at the center of most galaxies. A supermassive black hole several…
Astronomers Discover Double Star System That Flipped Planet-Forming Disk
New research that included astronomers Luca Matra and David J. Wilner of the Harvard-Smithsonian Center For Astrophysics has found the first confirmed example of a…
CHIME Detects Repeating Fast Radio Burst From Another Galaxy
Assistant professor of physics Laura Newburgh is part of a Canadian-led experiment that has detected the second-known example of a repeating fast radio burst (FRB)…
Scientists Find Evidence That Dark Matter Can Be Heated Up and Moved
Scientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies. The findings provide…
Astrophysicists Predict Milky Way is Headed For Catastrophic Collision
New research led by astrophysicists at Durham University, UK, predicts that the Large Magellanic Cloud (LMC) could hit the Milky Way in two billion years’…
PulChron System Measures Time Using Radio Pulses From Neutron Stars
ESA’s technical centre in the Netherlands has begun running a pulsar-based clock. The ‘PulChron’ system measures the passing of time using millisecond-frequency radio pulses from…
LIGO and Virgo Reveal Four New Sources of Gravitational Waves
Scientists have carried out a closer analysis of previously recorded data from the LIGO and Virgo gravitational wave detectors, tracking down four new signals. They…
New Equations Go Beyond Einstein’s Theory of General Relativity
When stars collapse, they can create black holes, which are everywhere throughout the universe and therefore important to be studied. Black holes are mysterious objects…
Astronomers Discover Unexpected Companion Around A Young Star
Astronomers have captured one of the most detailed views of a young star taken to date, and revealed an unexpected companion in orbit around it….
Voyager 2 Probe Enters Interstellar Space, Over 18 Billion Kilometers from Earth
For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the…
