Images from space show a dark spot on Mars’ surface where none was seen before, thought to be where the Schiaparelli lander crashed on Mars last Wednesday.
Is a hypothetical large planet – far beyond Neptune – causing a tilt in the sun? Plus, evidence for a 9th planet based on “extreme Kuiper Belt objects.”
The six most distant known objects in the solar system with orbits exclusively beyond Neptune (magenta) all mysteriously line up in a single direction. Also, when viewed in three dimensions, they tilt nearly identically away from the plane of the solar system. Batygin and Brown show that a planet with 10 times the mass of the earth in a distant eccentric orbit anti-aligned with the other six objects (orange) is required to maintain this configuration.

Astronomers use astronomical units – or AU – to describe solar system distances. Definition of AU here. Also, mean distances in AU to prominent solar system objects.
This little guy looks like a big-eyed mouse, but a new genetic analysis puts tarsiers on the branch of the primate evolutionary tree that leads to great apes and humans.

Details on the annual Orionid meteor shower. How and when to watch. In 2016, the peak mornings is October 21, but, by then, the moon will be in the way.
Joe Randall created this composite shot of the Orionid meteor shower from images taken on October 21, 2014. Thanks, Joe!
Look for Deneb Kaitos – brightest star in Cetus the Whale – highest in the sky around mid-evening.

The distant exoplanets known as “hot Jupiters” orbit their stars so tightly that they’re perpetually charbroiled. Plus they keep one face toward their stars.
“We have data coming back that allow us to fully understand the steps that did occur, and why the soft landing did not occur.” Meanwhile, the orbiter is A-OK.
