Interplanetary hoppers: Microbes from Earth may have reached Venus by hitchhiking on asteroids
If Venusian life does exist, it may have originated from Earth: An interplanetary hopper hitched a ride with an asteroid that grazed Earth’s upper atmosphere and landed on Venus. Researchers from Harvard University — astronomy professor Avi Loeb and student Amir Siraj — proposed the idea after a group of scientists recently detected signatures of phosphine. Microorganisms can produce […]

Heavy metal rain: Colossal “kilonova” explosions may be showering a nearby galaxy in gold and platinum
It’s not uncommon for cosmic objects such as stars to crash into each other. Such mergers generate massive explosions and send gravitational waves rippling through the cosmos. Mergers involving neutron stars are particularly strong. They result in a massive, turbocharged explosion called a kilonova that can be observed in nearly all space telescopes on Earth. An international […]

“Potentially hazardous” asteroid that flew by the Earth last week was discovered by amateur astronomer
On Sept. 10, a large, “potentially dangerous” asteroid safely passed by the Earth. Measuring roughly 3,280 feet wide, asteroid 2020 QU6 was large enough to cause global catastrophe had it actually impacted the planet. What’s more worrying, however, are the circumstances behind 2020 QU6’s discovery. The asteroid wasn’t discovered by national space agencies but by amateur astronomer Leonardo Amaral at the […]

Solar telescope offers unprecedented glimpse into the Sun
Scientists can take a better look at the Sun after a European team of researchers upgraded a solar telescope called GREGOR, located at the Teide Observatory in the Canary Islands. Recent observations using the telescope offer a spectacular, unprecedented glimpse into the Sun’s surface. An image captured magnetic structures, which resembled the craggy, golden texture of popcorn. Another […]

Astronomers: Dead star sent massive X-ray, radio waves to Earth
Fast radio bursts (FRBs) – super intense, millisecond-long bursts of radio energy waves produced by unidentified sources in the distant cosmos – are one of the most perplexing and rare mysteries in all of astronomy, having been detected a few dozen times by radio telescopes around the world. And now, one more has been observed […]

Recurring bursts of cosmic radio waves reach Earth yet again
Astronomers predicted that a mysterious fast radio burst would repeat this July or August. And it did, as predicted, according to recent observations of the fast radio burst (FRB) called FRB 121102. In June this year, an international group of researchers found that FRB 121102 repeats every 157 days. Such repeating FRBs are not unheard-of, however, this was […]

Astronomers develop new telescope system that can scan for signs of alien technology
Some astronomers believe that extraterrestrial beings are using extremely powerful flashlights to try and get humanity’s attention. If these supposedly advanced aliens are doing that, Earth finally has a way to find out with the help of the Very Energetic Radiation Imaging Telescope Array System (VERITAS), a collection of four telescopes, each 40 feet across, located […]

Astronomers debunk the mystery of Earth’s “space cones”
Earth is filled with cones that come from space. Fortunately, astronomers have figured out that they aren’t as mysterious as people previously believed – as it turns out, they’re just meteorites that plunged into the Earth’s atmosphere. Since the Earth began forming around 4.5 billion years ago, it has been peppered by asteroids and meteors alike. The […]

Birth of the “ploonet”: Scientists want to coin new term for cosmic objects that are a cross between a moon and a planet
Astronomers have coined a term for cosmic objects that are sort of a cross between a planet and a moon: a ploonet. According to researchers, ploonets can form when moons that have distant orbits with their planets suddenly break free from their orbits due to gravitational interactions. This causes the new ploonets to end up […]

Not just a fluke: Study confirms that the universe is expanding faster than expected
Since its explosive birth during the Big Bang, the universe has been expanding nonstop. Experts recently learned that the cosmos was growing faster than their original estimates. NASA-affiliated researchers went over Hubble Space Telescope data on distinct stellar types in the Milky Way’s nearest galactic neighbor. Observation of these distant stars made it possible to […]
