Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, according to new research. This shows that life could develop on Earth-like planets through the same mechanism at any time if atmospheric conditions are right.
A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico.
Using the same principles that make polarized sunglasses possible, a team of researchers at the Arecibo Observatory in Puerto Rico have developed a technique that will help better defend against asteroids on a collision course with Earth. A new study in The Planetary Science Journal found a better way to interpret radar signals bounced off asteroids' surfaces.
Comet Catalina is helping explain more about our own origins as it becomes apparent that comets like Catalina could have been an essential source of carbon on planets like Earth and Mars during the early formation of the solar system.
Ahmed AlHantoobi, an intern working with Northern Arizona University planetary scientists, assistant professor Christopher Edwards and postdoctoral scholar Jennifer Buz in NAU's Department of Astronomy and Planetary Science, led a study looking for answers to magnetic anomalies on Mars. The team explored the relationships between the strength of the magnetic field on the surface and the composition of the crust in the Terra Sirenum-Terra Cimmeria region of Mars.
After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.
Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.
According to a new study from the University of Copenhagen, Earth, Venus and Mars were created from small dust particles containing ice and carbon. The discovery opens up the possibility that the Milky Way may be filled with aquatic planets.
The latest observations from Insight-HXMT were published online in Nature Astronomy on Feb. 18. Insight-HXMT has discovered the very first X-ray burst associated with a fast radio burst (FRB) and has identified that it originated from soft-gamma repeater (SGR) J1935+2154, which is a magnetar in our Milky Way.
It forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it's known, left behind a crater off the coast of Mexico that spans 93 miles and runs 12 miles deep.
