"How would an alien observer see the Solar System?" asked an international team of astronomers, who estimated that there should be approximately ten currently undiscovered worlds which are favorably located to detect the Earth and are capable of sustaining life...
The coldest heart in the Solar System.
The visit of the interstellar interloper 1I/2017 U1, recently spotted streaking through the solar system, gives the people of Earth their first chance to study up close an object from another planetary system. In a study carried outShow More Summary
Exoplanets — that is, planets we know exist outside of our own Solar System — come in all shapes, sizes, and personalities. Some are super frigid, while others are boiling hot, and a few fall somewhere in between. A newly-discoveredShow More Summary
(Fundação de Amparo à Pesquisa do Estado de São Paulo) Objects scattered to the inner region of the Solar System by Jupiter's growth brought most of the water now found on Earth. Authors of an journal Icarus article describe a computational...Show More Summary
"An alien would spot three planets in our solar system in the habitable zone [Earth, Mars and Venus]," says research scientist Andrew Rushby, of NASA Ames Research Center, in Moffett Field, California. "Location alone isn't enough, but we know that...
A planet whole solar system is going to destroy the Earth during September October, uh, any time now, if the usual doomsday conspiracy people are to be believed. And if you're hoping to survive this calamity, you should probably know what's going on. More »
Interplanetary space is hardly tranquil. High-energy charged particles from the Sun, as well as from beyond our solar system, constantly whizz by. These can damage satellites and endanger astronaut health—though, luckily for life on Earth, the planet is blanketed by a protective magnetic bubble created by its magnetic field. Show More Summary
When our Sun erupts with giant explosions—such as bursts of radiation called solar flares—we know they can affect space throughout the solar system as well as near Earth. But monitoring their effects requires having observatories in many places with many perspectives, much the way weather sensors all over Earth can help us monitor what's happening with a terrestrial storm.
A strange visitor, either asteroid or comet, zipping through our solar system at a high speed is giving astronomers a once-in-a-generation opportunity to examine up close an object from somewhere else in our galaxy.
An Earth-sized planet has been discovered "only" 11 light-years from our solar system, astronomers announced in a study published Wednesday.
Modelling suggests that Pluto's atmospheric temperature is regulated by haze, unlike the other planetary bodies in the Solar System. The finding has implications for our understanding of exoplanetary atmospheres. See Letter p.352
Mars is one of the most studied and scrutinized of all the planets in our Solar System, and space agencies have sent probes, orbiters, and rovers to investigate it in unprecedented detail in recent years. Mankind has never found anything...Show More Summary
Introducing Ross 128 b.
While preparing for a conference talk/conversation I’m doing in Amsterdam this weekend, I was reading about the Golden Record that NASA sent along as a potential greeting from Earth to alien civilizations who might run across the Voyager probes in interstellar space millions of years from now.

Ross 128 b is the second-closest planet beyond our solar system and it has some similarities to Earth
Ross 128 b is a little farther away than Proxima b, the closest planet beyond our solar system, but it probably has better odds of being inhabitable.
(ESO) A temperate Earth-sized planet has been discovered only 11 light-years from the solar system by a team using ESO's unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. Show More Summary
E.ON has implemented a solar, wind and battery storage microgrid for a Swedish village.The southern village of Simris, which features 140 households, now gets its power from 500 kW of wind power, 440 kW of solar PV panels and an 800 kW battery.
