New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

In 2025, astronomers uncovered more than 100 new moons orbiting planets in our solar system, an exciting discovery that could help unlock the mysteries of planetary formation. As reported by New ...

For decades, astronomers have discovered hundreds of protoplanetary disks—structures believed to represent the early stages of our own solar system. However, most of these discoveries lie within our ...

Astronomers discovered a new moon of Uranus and hundreds of moons around Saturn over the past year, and there may be many ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

The post A Rare Interstellar Object Zooming Through Our Solar System Could Be Fundamental To Planets Of The Future first on ...

Peering through a cosmic keyhole at distant baby star, astronomers may have opened a new window on the deep past of our own solar system. Weighing in at 0.6 solar mass, HOPS-315 should someday grow to ...

Over 80% of exoplanetary systems with three or more planets exhibit a "peas-in-a-pod" architecture, characterized by similarly sized planets closely spaced and orbiting near their star. A new study ...

The solar system is 4.54 billion years old, based on rock dating. Gas giants (Jupiter and Saturn) likely formed first. Ice giants (Uranus and Neptune) probably formed next. Rocky planets formed last, ...

A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our ...
