Using The Big Bang As A Ruler Cosmologists use baryon acoustic oscillations to map distances as the universe expands

Baryon acoustic oscillations, an artifact remaining from the Big Bang, can be used by scientists to measure cosmological distances regardless of how the distances are changing. Soon after the Big Bang, the beginning of our universe, all of the matter READ MORE

An Interstellar Asteroid Just Flew Through Our Solar System Scientists are guessing the origins of an interstellar asteroid visitor they detected speeding through our solar system

An asteroid recently came blazing through our solar system and it appears to be an interstellar visitor. The asteroid, dubbed A/2017 U1, would be the first interstellar object ever to be observed within our own solar system. A/2017 U1 caught READ MORE

What Protects Exoplanets from Damaging Solar Flares? Simulating different models to understand which factors affect an exoplanet’s ability to sustain life during high-energy stellar events.

By Alexander Adranly Thanks to NASA’s Kepler Mission, over one-thousand potentially habitable exoplanets have been discovered to-date, orbiting around their respective stars. An exoplanet refers to any planet outside of our solar system. The discoveries of these worlds are a READ MORE

A New Field of Science: Space Pasta and Nuclear Crusts Astromaterial science studies nuclear pasta and Coulomb crystals in neutron stars

A new field of science is born – astromaterial science. First mentioned in today’s paper, this scientific field studies materials of astronomical objects that are denser than materials commonly found on Earth. Scientists, M. E. Caplan and C. J. Horowitz, READ MORE

Gravitational Waves from A Neutron Star Merger Shake the Earth and Astrophysics The LIGO/Virgo gravitational wave detection on Oct 16 leads to major leaps in understanding of astrophysics.

Big News! Astrophysics receives a gift. Interferometers at LIGO and Virgo detected gravitational waves coming from two neutron stars merging. This detection not only supports Einstein’s theory of relativity, but also teaches us even more about astrophysics that we didn’t know before.

The Sleeping Giant in a Small Town A supermassive black hole, 17 billion times the size of our Sun, was found in a small galaxy

Astronomers have uncovered a supermassive black hole, weighing 17 billion suns, in the middle of nowhere. This nearly record-breaking supermassive black hole is in the center of a small galaxy cluster, which is a small town by universe standards. At READ MORE

Two Black Holes Made a Mega Black Hole! An insight into the size of the gravitational wave as well as the benefit of three detectors

1.76 billion light years away, two black holes smashed into one another, bearing one huge black hole the size of 53 suns. The explosion from this merger created enormous distortions in spacetime, known as gravitational waves. These gravitational ripples have READ MORE

Have We Finally Found Dark Matter, or Merely Pulsars? The Fermi-LAT telescope experiment attempts to pinpoint the origin of an excess of gamma rays that might be a dark matter signal coming from the center of the Milky Way!

by Can Kilic Guest Contributor There is overwhelming evidence to support the existence of dark matter, but its existence is still a mystery to physicists. A method called Indirect detection remains one of our best hopes for experimentally detecting particles READ MORE

What Makes a Universe Habitable? A physics professor investigates what physical parameters cause a universe to be capable of harbouring life

If there are multiple universes, which of them are capable of harboring life and why? A physicist comes up with a number, and that number is the difference between the number of baryons and antibaryons in the universe. Find out what the heck this means by reading more!
