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…
Fast-Growing White Dwarf Surprises Astronomers
Astronomers have detected a bright X-ray outburst from a star in the Small Magellanic Cloud, a nearby galaxy almost 200,000 light years from Earth. A…
COSINE-100 Experiment Challenges Previous Claims About Dark Matter
Yale scientists are part of a new international experiment that challenges previous claims about the detection of non-luminous dark matter. Astrophysical evidence suggests that the…
LIGO Makes Vital Contribution to New Gravitational Wave Discoveries
Researchers from the University of Portsmouth have made vital contributions to the observations of four new gravitational waves, which were announced this weekend. The new…
GRAVITY Measures Environs of a Massive Black Hole Outside the Milky Way
Discovery is the first detailed observation of the environs of a massive black hole outside the Milky Way, say researchers from the GRAVITY group. In…
Scientists Discover Two Gravitationally Lensed Quasars
The path of light is bent by mass, an effect predicted by Einstein’s theory of gravity, and when a massive galaxy or cluster lies along…
MMS Spacecraft Provide First-Ever Views of Elusive Energy Explosion
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving “magnetic reconnection”—the process by which sparse particles and energy around Earth…
ALMA Views Galaxy-Scale Fountain in Full Glory
A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies…
GRAVITY Instrument Captures Observations of Material Orbiting Close to a Black Hole
ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky…
Astrophysicists Complete Polarimetric Investigation of Near-Earth Asteroid 3200 Phaethon
Polarimetric investigation of a near-Earth asteroid Phaethon was carried out in December 2017 on its closest approach to the Earth. The study was conducted in…
Gravitational Waves May Provide an Extremely Precise Measurement of the Universe’s Rate of Expansion
Twenty years ago, scientists were shocked to realize that our universe is not only expanding, but that it’s expanding faster over time. Pinning down the…
Measuring the Age of the Universe With Gravitational Waves
The single most important puzzle in today’s cosmology (the study of the universe as a whole) can be summarized in one question: How old is…
Hubble Program Views Superflares From Young Red Dwarf Stars
The word “HAZMAT” describes substances that pose a risk to the environment, or even to life itself. Imagine the term being applied to entire planets,…
SOFIA Observations Reveal Possible Key to Black Hole Activity
Collimated jets provide astronomers with some of the most powerful evidence that a supermassive black hole lurks in the heart of most galaxies. Some of…
Physicist Details the Shape of a Symmetrical Wormhole
A RUDN physicist demonstrated how to describe the shape of any symmetrical wormhole – a black hole that theoretically can be a kind of a…
Astronomers Discover a Luminous Blue Kilonova, GRB150101B
On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same…
