A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant. The hunt for planets beyond our solar system has turned up…
Fragile orbits of seven exoplanets limit late arrival of water. Seven Earth-sized planets orbit the star TRAPPIST-1 in near-perfect harmony, and U.S. and European researchers…
The internal compositions of rocky exoplanets correlate with that of their host stars, according to a new study, but not 1:1. This suggests that planet…
Stunning Yearly Observations Reveal Changes to Gas Giants’ Atmospheres In Greek mythology, a race of giants, called the Titans, first ruled the world. The ancient…
NASA’s James Webb Space Telescope Primed to Lift the Haze Surrounding Sub-Neptunes Detailed atmospheric studies will provide key insights into some of the most common…
Who hates deep sand traps more than golfers? Mars rover drivers (and probably Fremen too). When your vehicle is well over 50 million kilometers away…
A new technique developed in part by University of Hawaiʻi astronomer Nader Haghighipour has allowed scientists to quickly detect a transiting planet with two suns….
Whether Venus, one of the Solar System’s four terrestrial planets, ever had oceans remains an unsolved puzzle. Although an American study hypothesized that it did,…
Forming planets are one possible explanation for the rings and gaps observed in disks of gas and dust around young stars. But this theory has…
Jupiter’s iconic Great Red Spot (GRS) – a 16,000-kilometer-wide tempest that has been churning in the planet’s atmosphere for several centuries – extends deeper into…
Launching in 2029, NASA’s Deep Atmosphere Venus Investigation of Noble gases, Chemistry and Imaging (DAVINCI) mission will bring a rich suite of instruments to Venus…
Did Mars ever look like Earth? Yes, we think it did! Ancient Mars may have been wetter and warmer — similar to Earth. What happened?…
How common is our Solar System? Less common than we might think. A significant fraction of planetary systems around Sun-like stars have had a very…
An international team of astronomers led by scientists from Leiden University has for the first time characterized a dust disk surrounding a young super-Jupiter, which…
What are Lagrange points? They are places around a planet’s orbit where the gravitational pull of the planet and the Sun and the motion of…
Recently, astronomers have been finding protoplanetary discs around certain stars. Their discovery has helped kick off a new work in planetary formation theory. But planets…
The planets of the solar system all orbit the Sun more-or-less in a plane. Compared to the Earth’s orbit, which defines the plane at zero…
