Say hello to MK 2, our solar system’s newest moon

Say hello to MK 2, our solar system’s newest moon Some in the scientific community are still trying to do an exhaustive search of our own solar system, however, especially in the little-known area beyond Neptune.This week, NASA announced a new discovery in that effort to catalog local wanderers: a new moon they’ve nicknamed MK 2.

TRAPPIST-1: a star with three habitable planets, just 40 light years away

TRAPPIST-1: a star with three habitable planets, just 40 light years away The star is a so-called brown dwarf star, or a star that isn’t massive enough to exert the level of gravity needed to jump-start hydrogen fusion at its core.This means two things: It’s very cold (sometimes referred to as an ultra-cool dwarf star) and it doesn’t put out very much visible light.

NASA celebrates the Fourth of July with the arrival of its next-gen Jupiter probe

NASA celebrates the Fourth of July with the arrival of its next-gen Jupiter probe Thus was born the name for NASA’s Jupiter-exploring space probe, which just reached the gas giant this Fourth of July.The main goal of Juno is to better understand the evolution of Jupiter, and to use that to better understand the evolution of the solar system.

New data from Cassini reveals Titan has canyons filled with liquid methane

New data from Cassini reveals Titan has canyons filled with liquid methane It’s hard to describe Titan without getting a little breathless — the place is a little like Earth’s “upside down.As hydrocarbon rain turns into rivers and carve through the surface, canyons proportionate to our Grand Canyon run with flowing methane.

New evidence strengthens the case for ‘Planet 9’ in the outer solar system

New evidence strengthens the case for ‘Planet 9’ in the outer solar system In fact, we aren’t 100% sure we’ve found all the planets in our own solar system.In a new study published in The Astronomical Journal, scientists present compelling evidence for the existence of a large planet orbiting at the edge of the solar system.

The giant impact that created the Moon also seeded Earth with life-giving carbon

The giant impact that created the Moon also seeded Earth with life-giving carbon The story goes like this: About four and a half billion years ago, the Earth first settled together into a planet.According to the giant impact hypothesis, that massive body was Theia, and the impact sent a bolus of mashed-together molten planet sloshing into space, where it coalesced into the Moon.

Unexpected, mysterious x-rays found emanating from Pluto

Unexpected, mysterious x-rays found emanating from Pluto The image above may look like a blue blob, but it’s actually the dwarf planet Pluto.If this is confirmed, Pluto would be the most distant x-ray source in the solar system.

Earth is no longer the only planet with confirmed geological activity

Earth is no longer the only planet with confirmed geological activity And now, brand new insights into Mercury have confirmed Earth isn’t even the only geologically active planet.It’s not surprising that planets in general would have this attribute, but for Mercury scientists it is a surprise.

Closest exoplanet Proxima b remains mysterious, in the absence of direct observation

Closest exoplanet Proxima b remains mysterious, in the absence of direct observation The best we can do right now is make some educated guesses about conditions on Proxima b.According to researchers at France’s CNRS, there’s at least a possibility that Proxima b has liquid oceans on the surface.

NASA develops model to predict global dust storms on Mars

NASA develops model to predict global dust storms on Mars That’s why understanding the massive dust storms that can sometimes engulf the entire planet is so important.A new model of Mars’ dust storms has been published, and we’ll know in a few months if it can predict the next global storm.

Planet nine might be pulling our solar system out of alignment

Planet nine might be pulling our solar system out of alignment Their observations indicate that planet nine could be causing a “wobble” in the solar system.While we can’t see planet nine, astronomers have detected a number of bizarre effects in the solar system that could be explained by the object.
