When Comet Leonard, a mass of space dust, rock and ice about a half-mile (1 kilometer) wide, makes its closest pass of the Sun on Jan. 3, 2022, it will be a journey 40,000 years in the making. Ahead of its close pass, two ...
Last summer the SETI Institute began installing a second LaserSETI Observatory, this time 10,000 feet above sea level at Haleakala Observatory, thanks to the University of Hawai'i's Institute of Astronomy (IfA). As a result ...
According to multiple lines of evidence, Venus was once a much different planet than it is today. But roughly 500 million years ago, a massive resurfacing event triggered a runaway greenhouse effect that led to the poisonous ...
Are you trying to get into a morning routine for the new year? Venus is, too. The planet will undergo a transformation that only happens once every 584 days.

New modeling suggests large, high-speed impacts during Venus' early history could reconcile the differences between Venus and its rocky sister planet, Earth.
Now is the best time to get a glimpse of Comet C/2021 A1, better known as Comet Leonard. It's named for its discoverer, Gregory Leonard, a senior research specialist at the University of Arizona Lunar and Planetary Laboratory.
Earth's surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes called "volatile" elements, ...
With multiple rovers landed and a mission set to return samples to Earth, Mars has dominated the search for life in the solar system for decades. But Venus has some fresh attention coming its way.
An international team of researchers has found evidence that suggests possible volcanic activity involving Venuses' Idunn Mons. In their paper published in The Planetary Science Journal, the group describes the evidence they ...
