Webb's Picture of the Month Features Two Planet-Forming Disks and a Possible Planet
Two images of protoplanetary disks side-by-side. The left image shows a dark horizontal band covering the star, with broad, colorful, conical outflows above and below it, and a narrow jet
A Mercury Rover Could Explore the Planet by Sticking to the Terminator
A Mercury lander mission would create opportunities to sample unique geological features. However, extreme temperature fluctuations on Mercury’s surface pose challenges for exploration on the planetary surface. In a narrow
Improved thresholds and SSA accuracy can reduce most satellite collision risk
WASHINGTON — Improving the accuracy of space situational awareness (SSA) data and using tighter thresholds for potential conjunctions can help retire most of the risk of satellite collisions in low
A New Class of Star: Merger Remnant
In the vastness of the Universe, any new object with interesting properties can spur the search for similar objects, potentially establishing a new class of stars. In a paper published
