Study finds many heavy elements are created when neutron stars collide

Scientists know that elements lighter than iron are typically forged deep in the core of stars. The extremely high temperature in the core of stars can fuse protons allowing them to be smashed together, resulting in progressively heavier elements. One thing that has stumped scientists is what process creates heavy elements such as gold, platinum, and others.

Radio telescope detects signals emanating from stars suggesting planets

Radio telescope detects signals emanating from stars suggesting planets

Anytime we glance up at the night sky, we get an indication of just how vast and star-filled the universe is. Radio astronomers have leveraged the most powerful radio telescope in the world to detect stars sending out unexpected radio waves they believe may indicate the existence of unknown planets. Radio astronomers from the University of Queensland used the Low Frequency Array (LOFAR), part of ASTRON, the Dutch national observatory.

Astronomers predict Supernova Requiem will reappear in 2037

Astronomers predict Supernova Requiem will reappear in 2037

In the study of astronomy, it's difficult to predict many things that occur in the heavens. We can predict things like annual meteor showers and eclipses, but predicting other astronomical occurrences, such as supernovas, is something astronomers are frequently unable to do. For example, astronomers may know when certain stars appear to be preparing to explode into a supernova, but it's difficult or impossible to know exactly when that might happen.

Astronomers analyze a strange star hurtling towards the edge of the galaxy

Astronomers analyze a strange star hurtling towards the edge of the galaxy

Astronomers are currently studying the star known as LP 40−365. It's a breed of fast-moving star that is a remnant of a massive white dwarf that survived a massive supernova explosion. The star is currently about 2000 light-years away from Earth and is hurtling towards the edge of the Milky Way galaxy.

The tallest mountains on a neutron star are only millimeters high

The tallest mountains on a neutron star are only millimeters high

Here on Earth, mountains get extremely tall, thousands and thousands of feet high. However, new models of neutron stars show that the tallest mountains on these objects are only fractions of millimeters high due to the massive gravity of the incredibly dense objects. Neutron stars are some of the densest objects in the known universe, weighing about as much as the sun while being only about 10 kilometers across.

Astronomers discover a binary star system that will go supernova

Astronomers discover a binary star system that will go supernova

An international team of astronomers led by researchers from the University of Warwick has made a very interesting discovery. The team has discovered a binary star system that's heading towards supernova, which is very rare. The telltale sign of the binary system heading towards its demise is a teardrop-shaped star.

Betelgeuse’s Great Dimming has a great explanation

Betelgeuse’s Great Dimming has a great explanation

The mystery of Betelgeuse's "Great Dimming" has finally been answered, astronomers say, after new images of the surface of the distant star help explain why it unexpectedly darkened in late 2019. Betelgeuse, normally a bright orange star in the constellation of Orion, visibly dimmed and stayed that way through the first few months of 2020. Though it returned to its usual brightness by April 2020, scientists were left puzzled.

Astronomers discover a massive family of stars in the Milky Way

Astronomers discover a massive family of stars in the Milky Way

Glancing at the image below, it's clear that there are huge numbers of stars in the Milky Way. Astronomers say that the galaxy is filled with streams of stars, but one of those streams appears to have nearly 500 stars inside. Astronomers, on a new study, have discovered 8292 stellar streams in the galaxy.
