Scientists discover new data on fast radio bursts

Fast radio bursts (FRBs) were first discovered over ten years ago, and since their discovery, scientists have worked to figure out what could be generating the intense flashes of radio waves. Researchers have used a gradual process of elimination, and the field of possible explanations for FRBs has been narrowed as new information about them was gathered. The type of information researchers have been gathering includes how long the FRB lasts, the frequencies of the radio waves detected, and other tidbits.

Lyrid meteor shower peaks April 22

Lyrid meteor shower peaks April 22

Amateur skywatchers will want to be looking to the sky in the coming days, with the Lyrid meteor shower peaking on the morning of Thursday, April 22. Interestingly, that's also Earth Day. The meteor shower ends the four months of no meteors that range from January until April.

A total solar eclipse will happen in the US in 2024

A total solar eclipse will happen in the US in 2024

It's not often that eclipses block out the sun and can be viewed from the US. The rare events happen very infrequently, with the last occurring in 2017 for parts of Ohio. Prior to the 2017 solar eclipse, the last that was partly visible in parts of Ohio and the surrounding country, was in February 1979. The last solar eclipse seen across the entire 48 United States happened in June 1918.

A recently discovered black hole is the missing link between two different types

A recently discovered black hole is the missing link between two different types

Scientists have recently discovered a new black hole that is said to break a record not for being the smallest or the largest, but for being right in the middle between two known populations of black holes. The black hole recently discovered is part of the missing link between two known populations of black holes, small black holes made from stars and supermassive black holes in the center of most galaxies. The discovery was a joint effort between researchers from the University of Melbourne and Monash University.

Worlds with underground oceans could be more conducive to life than Earth

Worlds with underground oceans could be more conducive to life than Earth

Researchers from the Southwest Research Institute have put forward a new theory that says worlds with underground oceans could be more conducive to life than planets like Earth with surface oceans. The researcher says one of the most significant discoveries in planetary science in the last quarter decade has been worlds with oceans beneath layers of rock and ice are common in the solar system.

The black hole at the center of Messier 87 imaged in polarized light.

The black hole at the center of Messier 87 imaged in polarized light.

Astronomers have used the Event Horizon Telescope (EHT) to reveal a new view of the black hole at the center of the Messier 87 (M87) galaxy. The image shows how the black hole looks and polarized light and marks the first time astronomers have measured polarization so close to a black hole.

Gorgeous image of Messier 106 snapped using the Nicholas U. Mayall telescope

It's hard for anyone who's never looked through a large professional telescope to understand how you can get detailed views of such extremely distant galaxies and celestial bodies. Astronomers have shared a new image of galaxy Messier 106 that is breathtakingly beautiful and detailed. The images were taken using the Nicholas U. Mayall four-meter telescope at Kitt Peak National Observatory.

Astronomers use giant galaxy clusters as a lens to study distant radio galaxy

Astronomers use giant galaxy clusters as a lens to study distant radio galaxy

Radio telescopes are essentially massive and extremely sensitive radio receivers that can scan the heavens for extremely faint radio emissions coming from objects in the most distant parts of the universe. A team of astronomers recently used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to take advantage of naturally occurring phenomena to detect a distant galaxy believed to be the faintest radio-emitting object ever found. The team used distant clusters of galaxies as a natural lens to study objects even further away.

Researchers have found the strongest evidence yet of a black hole in motion

Researchers have found the strongest evidence yet of a black hole in motion

Astronomers have long theorized that supermassive black holes could travel through space but finding data to support that theory has been difficult. Researchers from the Center for Astrophysics | Harvard & Smithsonian have identified the clearest indication yet of a supermassive black hole in motion. The researchers say that it isn't expected for most supermassive black holes to be moving; they typically remain stationary.

Astronomers observe the most distant source of radio emissions ever

Astronomers observe the most distant source of radio emissions ever

Astronomers have used the European Southern Observatory's Very Large Telescope to discover and study in detail what they call the most distant source of radio emissions known. The source is a radio-loud quasar, which is a bright object with powerful jets emitting at radio wavelengths. The quasar is so far away it has taken 13 billion years for the light to reach Earth.

Sky survey map shows tens of thousands of supermassive black holes

Sky survey map shows tens of thousands of supermassive black holes

An international team of astronomers has published a new map of the sky and within that map is more than 25,000 supermassive black holes. The map is the most detailed celestial map in the field of low radio frequencies. It was built by astronomers using 52 stations with LOFAR antennas across nine European countries.

Cygnus X-1 contains a surprisingly massive black hole

Cygnus X-1 contains a surprisingly massive black hole

The image below is an artist's impression of the Cygnus X-1 system, which contains the most massive stellar-mass black hole we have ever detected without the use of gravitational waves. The massive black hole in the system is 21 times the mass of the sun. Cygnus X-1 is one the closest black holes to Earth and was initially discovered in 1964.
