Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid mantle.
The discovery of a planet similar to Venus around a star in the neighborhood of the solar system raises hopes that astronomers may someday unlock the secret to why life appeared on Earth.
First came a rare solar eclipse, followed by the northern lights, fueled by a solar storm. The next celestial phenomenon will come next month, when skygazers can look forward to an alignment known as a "planetary parade."
NASA's Psyche spacecraft passed its six-month checkup with a clean bill of health, and there's no holding back now. Navigators are firing its futuristic-looking electric thrusters, which emit a blue glow, nearly nonstop as ...
People might assume the search for life on Mars ended when NASA's first rovers sent back images of the planet's barren, inhospitable surface. However, as scientists broaden their understanding of the extreme conditions in ...
A team of astronomers at Nanjing University has found evidence that Mars likely has more potentially hazardous asteroids in its path than Earth. In their study, posted on the arXiv preprint server, the group investigated ...
It's tiny, but it's there. By now, we're all used to seeing amazing photos of Jupiter courtesy of NASA's Juno mission on a routine basis. Many of these are processed by volunteer "citizen scientists," and they show the swirling ...
In February 2022, SpaceX and entrepreneur/philanthropist Jared Isaacman (commander of the Inspiration4 mission) announced they were launching a new program to "rapidly advance human spaceflight capabilities" while supporting ...
Although Mars presents a barren, dusty landscape with no signs of life so far, its geological features such as deltas, lakebeds, and river valleys strongly suggest a past where water once flowed abundantly on its surface. ...
Even though Venus and Earth are so-called sister planets, they're as different as heaven and hell. Earth is a natural paradise where life has persevered under its azure skies despite multiple mass extinctions. On the other ...
