Earthlike planets should readily form around other stars, meteorites suggest
How hard is it to give birth to an Earth? To assemble the right mix of rock, metal, and water, in a balmy spot not too far from a star? For a long time, planetary scientists have thought Earth was a lucky accident, enriched with water and lighter “volatile” elements—such as nitrogen and carbon—by asteroids

By Dr. Rudi Kuhn, South African Astronomical Observatory December 14, 2022Illustration of Saturn and its rings. All of the outer gas giant planets — Jupiter, Saturn, Neptune, and Uranus — have rings around them.Planets are surrounded by rings because they are made up of particles that orbit the planet. These particles can be made up

Recycling one of the planet’s trickiest plastics just got a little easier
Polyethylene is one of the world’s most commonly used plastics, found in bottles and packaging film, but it’s also one of the hardest to break down. By itself, it would take polyethylene hundreds of years to completely decompose. Scientists have been working to tackle this problem as polyethylene trash is clogging up landfills and littering

If you were to picture what it would be like on one of these distant worlds, or exoplanets, your mental image would probably include a parent star—or more than one, especially if you're a Star Wars fan. But scientists have recently discovered that more…

Planets Are Born from Dust Trap Rings
December 30, 2021
The ALMA telescope, in Chile, sensitive to millimeter-sized dust, took these images of planet-forming disks.ALMA (ESO/NAOJ/NRAO), S. Andrews et al.; NRAO/AUI/NSF, S. DagnelloAll we are is dust in the wind, man. The same goes for the planets and asteroids and comets. Starting from our dusty beginnings, gravity and a mess of other forces conspired to…
Study: Planets gone rogue could sustain life
Credit: Pixabay/CC0 Public Domain A rogue planet is an interstellar object of planetary mass without a host planetary system. As they freely roam around space, could they be fertile nurseries for life? A Florida Tech scientist believes it's possible based on extensive research he has undertaken over the past several years. In research highlighted this…
