Astronomers spotted a distant planet in the middle of making its own moon

Astronomers have captured a distant planet adorned with a moon-making disc for the first time. The planet has captured enough gas and dust in its orbit to make three moons the size of Earth's. By studying this world and its star, astronomers can learn more about how planets and moons are born. LoadingSomething is loading. For the first time, as...

Scientists spotted jets of hot gas whizzing out of a supermassive black hole at the heart of a nearby galaxy

Astronomers imaged jets of hot gas swirling out of a black hole at the heart of a nearby galaxy. Their findings suggest that all jets resemble one another, regardless of their black hole's mass. In 2019, the same researchers zoomed in on a black hole 6.5 billion times the mass of our sun. LoadingSomething is loading. At the heart of every gala...

NASA’s Hubble Space Telescope photographed colliding galaxies after recovering from a month-long mystery glitch

LoadingSomething is loading. The Hubble Space Telescope is back, and NASA has the pictures to prove it.The Earth-orbiting observatory went offline on June 13 and stayed that way for more than a month while engineers struggled to identify a mysterious glitch. NASA still hasn't announced what exactly caused the problem, but the agency's engineers managed to br...

NASA is about to switch its Hubble Space Telescope to backup hardware — a’risky’ maneuver to save its life

After a month of head-scratching, NASA engineers finally think they've identified the glitch that took out the world's most powerful space telescope more than a month ago.The Hubble Space Telescope, which launched into orbit in 1990, has captured images of the births and deaths of stars, discovered new moons around Pluto, and tracked two interstellar objects as they zipped through our solar system. Its observations have allowed astronomers to calculate the age and expansion of the universe and to peer at galaxies formed shortly after the Big Bang.But the telescope has been offline since June 13, when one of its main computers stopped working. NASA engineers have spent the last month running diagnostic tests and analyzing data...

The Perseids start this week, and NASA calls it the best meteor shower of the year. Here’s how to watch.

NASA calls the annual Perseids meteor shower the best of the year, thanks to the many bright meteors that streak across the night sky.This year, the Perseids shower is predicted to peak on August 11 and 12, according to EarthSky. On those nights, people could see up to 100 meteors per hour as Earth plows through a cloud of cometary debris. That dwarfs the rate of meteors during all other annual showers.But the Perseids are active for about 40 days every summer — between July 14 and August 24 this year. So starting this week, there should be some meteor activity each night starting shortly after twilight.The Perseid meteors are known both for their epic "fireballs" — explosions of light and color that last longer than those fr...

Mars and Venus will appear just a finger’s width apart in the night sky on Monday and Tuesday. Here’s how to see it.

Mars and Venus are about to line up in the night sky, getting so close on Monday and Tuesday that they'll almost seem to touch.An astronomical event in which celestial bodies align in the sky like this is called a conjunction.All month, Mars and Venus have been creeping nearer to one another. After sunset on Monday night, the two planets will appear so close together that a full moon couldn't fit in between. That's just a finger's width apart if you hold your hand up to the sky, according to NASA. The two planets will actually get closest together in the early hours of Tuesday morning, but daylight will make that impossible to see. So instead, people will have to wait until after the sun sets on Tuesday to see the two planets...

Even the Hubble Space Telescope’s backup computer is glitching now — raising new questions about what’s gone wrong

LoadingSomething is loading. NASA has been trying to figure out what's wrong with the Hubble Space Telescope for nearly two weeks, but the mystery just deepened.Hubble, which launched into orbit in 1990, is the world's most powerful space telescope.
