Viewed from the Voyager 1 space probe as it passed beyond the edge of the solar system, Earth and Venus might not look too different—same diameter, similar mass and distance from the sun.
Astrophysicists have used the James Webb Space Telescope (JWST) to take a close look at a volatile star.
The ability to have access to the Internet or use a mobile phone anywhere in the world is taken more and more for granted, but the brightness of Internet and telecommunications satellites that enable global communications ...
As of October 2023, astronomers have discovered 5,506 exoplanets orbiting other stars. That number is growing daily, and astronomers are hoping, among other things, to find Earth-like worlds. But will we know one when we ...
The Parker Solar Probe is the little engine that just keeps going and going by the sun. On September 27th, it made its 17th close approach and skimmed just 7.26 million kilometers (4.51 million miles) above the sun's "surface" ...
Venus may be a (slightly) gentler place than some scientists give it credit for.
The Earth's crust continued a slow process of reworking for billions of years, rather than rapidly slowing its growth some 3 billion years ago, according to a Penn State-led research team. The new finding contradicts existing ...
At their closest point in orbit, Earth and Jupiter are separated by almost 600 million kilometers. At the time of writing, five months after launch, Juice has already traveled 370 million kilometers, yet in time it's only ...
With its crushing atmospheric pressure, clouds of sulfuric acid, and searing surface temperature, Venus is an especially challenging place to study. But scientists know that observing its surface can provide key insights ...
Are we alone? This question is nearly as old as humanity itself. Today, this question in astronomy focuses on finding life beyond our planet. Are we, as a species, and as a planet, alone? Or is there life somewhere else?
