Distant rocky planets may have chemical makeups nothing like Earth's | Science News

If a real Captain Kirk ever blasts off for other stars in search of rocky planets like ours, he may find lots of strange new worlds whose innards actually bear no resemblance to Earth's.

A smattering of heavy elements sprinkled on 23 white dwarf stars suggests that most of the rocky planets that once orbited the stars had unusual chemical makeups , researchers report online November 2 in Nature Communications .

Simulations provide clue to missing planets mystery -- ScienceDaily

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 trouble explaining why it is rare to find planets associated with rings.

Young stars are encircled by protoplanetary disks of gas and dust. One of the world's most powerful radio telescope arrays, ALMA (Atacama Large Millimeter/submillimeter Array), has observed a variety of patterns of denser and less dense rings and gaps in these protoplanetary disks.

Astronomers May Have Discovered a Planet in Another Galaxy

Astronomers detected the temporary dimming of X-rays from a system where a massive star is in orbit around a neutron star or black hole (shown in the artist’s illustration).

Spotting a planet in another galaxy is hard, and even though astronomers know that they should exist, no planetary systems outside of the Milky Way have been confirmed so far.

Bad Astronomy | Asteroid impacts on the Moon may have come from Earth's formation | SYFY WIRE

There's a popular hypothesis among planetary scientists that, very early in our solar system's history, the migration of gas giants like Jupiter and Saturn threw a huge wave of giant asteroids into the inner solar system.

This impact wave, called the Late Heavy Bombardment (or LHB) is fairly well established. But a new paper just published by a pair of planetary scientists throws doubt on the idea that it was caused by the outer planets.
