Astronomers identify a new type of star explosion called a magneto-rotational hypernova

Astronomers identify a new type of star explosion called a magneto-rotational hypernova

An international team of astronomers has discovered the first evidence of the destruction of a collapsed and rapidly spinning star in a phenomenon they have called a magneto-rotational hypernova. This is a new type of explosion that was previously unknown and is said to have occurred only about a billion years after the Big Bang. Researchers believe the new type of explosion is the most likely explanation for the presence of unusually high amounts of some elements detected in another extremely ancient and primitive Milky Way star.

Kepler telescope uncovers evidence of planets not tied to a host star

Kepler telescope uncovers evidence of planets not tied to a host star

The Kepler telescope has discovered evidence suggesting there are free-floating planets that are alone in deep space, unbound to any host star. The data shows four new discoveries consistent with planets having similar masses to Earth that are free-floating in deep space. The study was led by Iain McDonald from the University of Manchester and used data gathered in 2016 during the K2 phase of the NASA Kepler Space Telescope.

Unique features of Palomar 5 could be the result of an oversized black hole population

Unique features of Palomar 5 could be the result of an oversized black hole population

Among the star clusters in our galaxy, Palomar 5 is one of the most unique. It's described as the "fluffiest" cluster in the halo of the Milky Way, with an average distance between stars in the cluster only a few light-years apart. Palomar 5 also has a unique stellar stream associated with it, spanning more than 20 degrees across the sky. A recent paper published by a group of astronomers and astrophysicists led by the University of Barcelona has shown that both of those distinguishing features of Palomar 5 are likely the result of a large black hole population.

Square Kilometer Array radio telescope networks to begin construction

Square Kilometer Array radio telescope networks to begin construction

Two new radio telescope networks have been approved for construction by the SKA Observatory (SKAO). SKAO member states voted to approve the construction of the SKA telescopes in Australia and South Africa. The pair of telescope networks is currently designated SKA-Low and SKA-Mid, with the names describing the radio frequency ranges each network will cover.

Astronomers discover a small yet massive white dwarf star

Astronomers discover a small yet massive white dwarf star

Astronomers had discovered a white dwarf star that is a bit of a contradiction. It's small, but at the same time, it's the most massive white dwarf ever seen. The star was formed when two less massive white dwarfs merged and is about 4300 kilometers across, making it slightly larger than the moon.

Scientists discover a third transiting exoplanet orbiting a distant star

Scientists discover a third transiting exoplanet orbiting a distant star

The ESA has an exoplanet-hunting satellite in orbit called CHaracterising ExOPlanet Satellite or CHEOPS. Scientists were investigating a pair of previously known planets orbiting around a distant star when they unexpectedly saw a third exoplanet transit the star. The transit observed will reveal details about the strange planet researchers on the project described as being "without a known equivalent."

Astronomers believe there may be more Earth-sized planets than they thought

Astronomers believe there may be more Earth-sized planets than they thought

Some astronomers believe that exoplanet searches may be missing nearly half of all Earth-sized planets orbiting other stars. The findings by astronomers suggest that Earth-sized planets could be undiscovered in binary star systems hidden by the glare of the parent stars. Scientists note that roughly half of all stars are binary systems meaning they could be overlooking vast numbers of Earth-sized planets.

A mysterious comet is entering our solar system for the first time

A mysterious comet is entering our solar system for the first time

Every now and then, astronomers discover something in the cosmos that has never been seen before. Such was the case recently when scientists discovered a new object which has only recently been confirmed to be a comet. The new comet is called Bernardinelli-Bernstein, and astronomers investigating the object have determined it has an orbit that takes 5.5 million years to complete.

Scientists glean planet formation secrets by studying a young and chaotic star system

Scientists glean planet formation secrets by studying a young and chaotic star system

Scientists have used the Atacama Large Millimeter/submillimeter Array (ALMA) to study a very young star system called Elias 2-27. The team has shed light on some mysteries of planet formation by confirming that gravitational instabilities play a key role in planet formation. For the first time, researchers directly measured the mass of a protoplanetary disk using gas velocity data.

Astronomers map motion in galaxies spanning hundreds of millions of light-years

Astronomers map motion in galaxies spanning hundreds of millions of light-years

A group of scientists comprised of astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP), with help from scientists in China and Estonia, have mapped the motion of galaxies via huge filaments that connect the cosmic web. Researchers have found that these long tendrils of galaxies spin on a scale spending hundreds of millions of light-years. The rotation is said to be on enormous scales never before seen.

A gigantic arc of galaxies has been discovered spanning 3.3 billion light-years

A gigantic arc of galaxies has been discovered spanning 3.3 billion light-years

Astronomers have made a very interesting discovery that has been dubbed the Giant Arc. The newly discovered crescent of galaxies spans 3.3 billion light-years and is described as one of the largest known structures in the universe. The massive size of the ark of galaxies is challenging some of the basic assumptions astronomers hold about the cosmos.

Giant blinking star discovered at the center of the galaxy dubbed VVV-WIT-08

Astronomers have discovered what they call a giant "blinking" star towards the center of the Milky Way galaxy. The star is called VVV-WIT-08, and it's 25,000 light-years away from Earth. The mysterious star was observed in the sky as it decreased in brightness by a factor of 30, making it almost disappear from the sky.
