We live in a mature solar system—eight planets and several dwarf planets (like Pluto) have formed, the latter within the rock- and debris-filled region known as the Kuiper Belt. If we could turn back time, what would we see as our solar system formed? While we can’t answer this question directly, researchers can study other systems that are actively forming—along with…

A surprising find of fast-moving gas from a young star
Fast-moving gas from a young star – located in a star-forming region 400 light-years away – is giving astronomers insight into how planets form. Source: https://earthsky.org/space/no-lup-surprising-find-outflowing-gas-young-star…
NASA re-establishes contact with Voyager 2 spacecraft
On October 29, NASA re-established contact with its Voyager 2 spacecraft, after the probe was left flying solo for 7 months while repairs were made to the radio antenna in Australia used to control it. Source: https://earthsky.org/space/nasa-reestablishes-contact-with-voyager2-spacecraft-oct2020…
New evidence our neighborhood in space is stuffed with hydrogen
Only the two Voyager spacecraft have ever been there, and it took than more than 30 years of supersonic travel. It lies well past the orbit of Pluto, through the rocky Kuiper belt, and on for four times that distance. This realm, marked only by an invisible magnetic boundary, is where Sun-dominated space ends: the closest reaches of interstellar space. Source:…
NASA’s Webb to examine objects in the graveyard of the solar system
Beyond the orbit of Neptune, a diverse collection of thousands of dwarf planets and other relatively small objects dwells in a region called the Kuiper Belt. These often-pristine leftovers from our solar system’s days of planet formation are called Kuiper Belt objects, or trans-Neptunian objects. NASA’s upcoming James Webb Space Telescope will examine an assortment of these icy bodies in a…
Astronomers discover activity on distant planetary object
Centaurs are minor planets believed to have originated in the Kuiper Belt in the outer solar system. They sometimes have comet-like features such as tails and comae—clouds of dust particles and gas—even though they orbit in a region between Jupiter and Neptune where it is too cold for water to readily sublimate, or transition, directly from a solid to a gas….
Lighting a path to find Planet Nine
The search for Planet Nine – a hypothesized 9th planet in our solar system – may come down to pinpointing the faintest orbital trails in an incredibly dark corner of space. Source: https://earthsky.org/space/lighting-path-to-find-planet-nine…
What are comets?
Comets are loosely packed balls of ice and dust orbiting our sun, that sometimes become visible in Earth’s skies. A comet’s tail may stretch across millions of miles of space. Source: https://earthsky.org/astronomy-essentials/definition-what-are-comets…
5 years after New Horizons flyby, 10 cool things about Pluto
Here are 10 of the coolest, weirdest and most unexpected findings about the Pluto system scientists have learned thanks to the New Horizons spacecraft’s flyby of the distant world in 2015. Source: https://earthsky.org/space/new-horizons-flyby-10-cool-things-about-pluto…
Wowzer! Pluto spacecraft sees parallax for Proxima
