Strange objects from other star systems are visiting our solar system. These interstellar visitors are scientifically valuable but disappear quickly. Scientists are calling for a global response ...

Two new studies, based on observations made with ESO’s telescopes, show that objects only a few times more massive than Jupiter are born with discs of dust and gas, the raw material for planet making.

Long ago, a planetary object eight times the mass of Jupiter may have once visited the solar system and altered the orbits of the four outer planets-Jupiter, Saturn, Uranus, and Neptune. It could ...

The Planetary Society continues to fund the search for potentially hazardous comets and asteroids that orbit close to our planet by awarding Gene Shoemaker Near Earth Object Grants to five researchers ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects – some of which could strike the Earth — ended its mission and burned on reentering the atmosphere after ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

There are few cosmological concepts which have gripped the public — and Hollywood — more tightly than the idea of an incoming asteroid. Huge chunks of rock headed for Earth with the potential to ...

Here’s an object that’s a lot of fun to show to others at summer and fall star parties. Through 8-inch and smaller telescopes, the Blinking Planetary (NGC 6826) in Cygnus appears to blink when viewed ...
