California wildfires threaten SETI radio telescope array

California wildfires threaten SETI radio telescope array

This summer has been a terrible wildfire season around the United States. Perhaps the hardest-hit state of all has been California, where drought and extremely dry conditions along with high winds have stoked wildfires that have destroyed homes and businesses all around the state. SETI Institute is well known for using a radio telescope array to search the galaxy for extraterrestrial life.

Mysterious repeating radio signal discovered in the center of the Milky Way

Mysterious repeating radio signal discovered in the center of the Milky Way

Astronomers have discovered something in the center of the Milky Way galaxy that has left them baffled. The team has detected a repeating radio signal near the center of our galaxy that they say is unlike any radio signal seen before. Researchers are sure the radio signal isn't a fast radio burst, a pulsar, or a low-mass star.

Astronomers say some white dwarfs may look younger than they actually are

Astronomers say some white dwarfs may look younger than they actually are

Astronomers made new discoveries that challenge some old notions about white dwarfs. Astronomers have used new data gathered by the Hubble Space Telescope to determine that white dwarfs may continue to burn hydrogen in the final stages of their lives. By burning hydrogen in the latter stages of their lives, white dwarfs may appear to be more youthful when viewed than they are.

Blazing fast asteroid orbits the sun in 113 days

Blazing fast asteroid orbits the sun in 113 days

Astronomers have discovered what they say is the fastest orbiting asteroid in the solar system. The asteroid orbits the sun in 113 days, giving it the shortest known orbital period for an asteroid and the second shortest orbital period for any object in the solar system. The only object in the solar system with a faster orbital period than the new asteroid, called 2021 PH27, is the planet Mercury.

New and extremely detailed images of distant galaxies are beautiful

New and extremely detailed images of distant galaxies are beautiful

Astronomers issued some extremely detailed and beautiful images of distant galaxies. The images offer detail not seen in images of these galaxies in the past. While the images are certainly beautiful to look at, their incredible detail gives astronomers insight into how galaxies work.

Perseids meteor shower is gearing up to be a spectacle in the nighttime sky

Perseids meteor shower is gearing up to be a spectacle in the nighttime sky

Each year, the Earth moves through the tail of a comet leading to the Perseid meteor showers that start in late July and peak by the middle of August. The first meteor of the shower for 2021 was observed on July 26. NASA says anyone wanting to look at the skies and see the meteor shower for themselves would find the best viewing on the night of August 11.

Astronomers investigate the layered atmosphere of a brown dwarf

Astronomers investigate the layered atmosphere of a brown dwarf

In our solar system, Jupiter is the biggest planet of them all. It's a massive gas giant, many times larger than Earth. Despite how large Jupiter is and its stature as the biggest planet in our solar system, it's very small compared to some gas giants orbiting other stars. These types of supermassive planets are known as super-Jupiters and can weigh up to 13 times Jupiter's mass.

Astronomers capture first spin measurements of planets in the HR 8799 star system

Astronomers capture first spin measurements of planets in the HR 8799 star system

Astronomers have been studying a star system discovered in 2008 by the W. M. Keck Observatory and Gemini Observatory from Hawaii. The star system is called HR 8799 and is 129 light-years away from Earth. Within that star system is a quartet of planets, all known as super-Jupiters.

Astronomers have detected new areas of star formation in the Milky Way

Astronomers have detected new areas of star formation in the Milky Way

Astronomers used two of the most powerful radio telescopes in the world to make a very detailed and sensitive image of a large segment of the Milky Way galaxy. Astronomers were able to detect previously unseen tracers indicating massive star formation by using the radio telescopes. The telescopes used in the study included the Karl G. Jansky Very Large Array (VLA) and the 100-meter Effelsberg Telescope in Germany.

Amateur astronomer discovers a new Jovian moon

Amateur astronomer discovers a new Jovian moon

Everyone knows that the Earth only has one moon orbiting the planet. We all get to see it most nights, no matter where we are on the globe. While Earth has only one moon, other planets have significantly more. Jupiter for instance, has 79 known moons and may have one more.

ESO astronomers share galaxy images that look like fireworks

ESO astronomers share galaxy images that look like fireworks

A team of astronomers from the European Southern Observatory (ESO) have released some new observations of galaxies that look like colorful explosions of fireworks in the sky. The images were obtained using the ESL Very Large Telescope (VLT) and show different components of each galaxy in distinct colors. The multiple colors allow astronomers to pinpoint the locations of young stars and the warm gas they produce around them.

Astronomers finally solve a decades-old mystery surrounding Jupiter’s x-ray bursts

Astronomers finally solve a decades-old mystery surrounding Jupiter’s x-ray bursts

A group of researchers has solved a mystery that has lingered for 40 years of how Jupiter produces bursts of x-rays every few minutes. The team says the x-rays are part of Jupiter's aurora, which are bursts of visible and invisible light occurring when charged particles interact with the atmosphere of the massive planet. On Earth, auroras happened as well and are more commonly known as the northern lights.
