Boiling Water Is Carving Martian Slopes

Finding water on Mars is a primary focus of human efforts to understand the Red Planet. The presence of liquid water on Mars supports the theory that life existed there. Now it looks as though some puzzling features on the surface of Mars could have been caused by boiling water. Recurring slope lineae (RSL) are dark streaks found on slopes on the surface of Mars. It was thought that these streaks could have been caused by seasonal melting. Other proposed causes were dust avalanches or the venting

James Webb Space Telescope Takes The Gloves Off

The James Webb Space Telescope (JWST) isn't even operational yet, and already its gleaming golden mirror has reached iconic status. It's segmented mirror is reminiscent of an insect eye, and once that eye is unfolded at its eventual stationary location at L2, the JWST will give humanity its best view of the Universe yet. Now, NASA has unveiled the JWST's mirrors in a clean room at the Goddard Space Flight Centre, giving us a great look at what the telescope will look like when it's operational. E

Bayesian Analysis Rains On Exoplanet Life Parade

... ask. A lot of space science and space missions are pointed directly at that question. The Kepler mission is designed to find exoplanets, which are planets orbiting other stars. More specifically, its aim is to find planets situated in the habitable zone around their star. And it's done so. The Kepler mission has found 297 confirmed and candidate planets that are likely in the h

Chinese Space Baby Research Lands In Mongolia

We've solved many of the problems associated with space travel. Humans can spend months in the zero-gravity of space, they can perform zero-gravity space-walks and repair spacecraft, they can walk on the surface of the Moon, and they can even manage, ahem, personal hygiene in space. We're even making progress in understanding how to grow food in space. But one thing remains uncertain: can we make baby humans in space?According to a recent successful Chinese experiment, the answer is a tentative

An Earth-like Planet Only 16 Light Years Away?

Earth may have a new neighbour, in the form of an Earth-like planet in a solar system only 16 light years away. The planet orbits a star named Gliese 832, and that solar system already hosts two other known exoplanets: Gliese 832B and Gliese 832C. The findings were reported in a new paper by Suman Satyal at the University of Texas, and colleagues J. Gri?th, and Z. E. Musielak. Gliese 832B is a gas giant similar to Jupiter, at 0. 64 the mass of Jupiter, and it orbits its star at 3. 5 AU. G832B proba

Our Sun May Have Eaten A Super Earth For Breakfast

Our Solar System sure seems like an orderly place. The orbits of the planets are predictable enough that we can send spacecraft on multi-year journeys to them and they will reliably reach their destinations. But we've only been looking at the Solar System for the blink of an eye, cosmically speaking. The young Solar System was a much different place. Things were much more chaotic before the planets settled into the orbital stability that they now enjoy. There were crashings and smashings aplenty

Gravity Waves On Pluto?

New Horizons' historic journey to Pluto and beyond continues to provide surprises. As data from the spacecraft's close encounter with Pluto and its moons arrives at Earth, scientists are piecing together an increasingly intriguing picture of the dwarf planet. The latest discovery is centred around Pluto's atmosphere, and what are called 'atmospheric gravity waves.'Atmospheric gravity waves are a different phenomenon than the gravity waves that were detected for the first time in February, 2016.

A Super-Fast Star System Shrugs Its Shoulders At Physics

Astronomers have found a pair of stellar oddballs out in the edges of our galaxy. The stars in question are a binary pair, and the two companions are moving much faster than anything should be in that part of the galaxy. The discovery was reported in a paper on April 11, 2016, in the Astrophysical Journal Letters. The binary system is called PB3877, and at 18,000 light years away from us, it's not exactly in our neighborhood. It's out past the Scutum-Centaurus Arm, past the Perseus Arm, and even
