Yesterday, NASA’s Mars InSight lander successfully touched down on the Martian surface after spending seven long months in space. Over the course of the next few hours, the lander began the surface operations phase of its mission, which involved deploying its solar arrays. The lander also managed to take some pictures of the surface, which showed the region where it will be studying Mars’ interior for the next two years.
Our long fascination with the journey to Mars
What planet Earth might look like when the next supercontinent forms – four scenarios
The outer layer of the Earth, the solid crust we walk on, is made up of broken pieces, much like the shell of a broken egg. These pieces, the tectontic plates, move around the planet at speeds of a few centimetres per year. Every so often they come together and combine into a supercontinent, which remains for a few hundred million years before breaking up. The plates then disperse or scatter and move away from each other, until they eventually – after another 400-600 million years – come back together again.

InSight Is Catching Rays on Mars
NASA's InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA's Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight's landing site.

Is alcohol bad for you? It depends on the drink and how you drink it
Recent headlines claim that a glass of wine or a pint of beer a day shortens your life. It’s enough to dampen any thoughts of a celebratory drink or two at Christmas. But those conclusions are based on a partial view of the alcohol debate.
How we discovered that supermassive black holes can power enormous ‘galactic fountains’
A fountain in a garden pond could shoot a plume of water to roughly three metres in height. By comparison, the famous fountain on Lake Geneva launches a plume of water up to 140m into the air. Now imagine a fountain launched from the centre of a galaxy, with a supermassive black hole acting as the pump. How far do you think this plume would extend? The answer is over 100,000 light years.
What Two Planetary Siblings Can Teach Us About Life
NASA's Lucy in the Sky with … Asteroids?
A little over 4 billion years ago, the planets in our solar system coexisted with vast numbers of small rocky or icy objects orbiting the Sun. These were the last remnants of the planetesimals – the primitive building blocks that formed the planets. Most of these leftover objects were then lost, as shifts in the orbits of the giant planets scattered them to the distant outer reaches of the solar system or beyond. But some were captured in two less-distant regions, near points where the gravitational influence of Jupiter and the Sun balance, and have remained trapped there, mostly untouched, for billions of years.

Exploding Stars Make Key Ingredient Found in Glass
We are all, quite literally, made of star dust. Many of the chemicals that compose our planet and our bodies were formed directly by stars. Now, a new study using observations by NASA's Spitzer Space Telescope reports for the first time that silica — one of the most common minerals found on Earth — is formed when massive stars explode.

How NASA Will Know When InSight Touches Down
NASA InSight Team on Course for Mars Touchdown
NASA's Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) spacecraft is on track for a soft touchdown on the surface of the Red Planet on Nov. 26, the Monday after Thanksgiving. But it's not going to be a relaxing weekend of turkey leftovers, football and shopping for the InSight mission team. Engineers will be keeping a close eye on the stream of data indicating InSight's health and trajectory, and monitoring Martian weather reports to figure out if the team needs to make any final adjustments in preparation for landing, only five days away.
Chinese Fusion Experiment Reaches 100 Million Degrees
Fusion power has been the fevered dream of scientists, environmentalists and futurists for almost a century. For the past few decades, scientists have been attempting to find a way to create sustainable fusion reactions that would provide human beings with clean, abundant energy, which would finally break our dependence on fossil fuels and other unclean methods.
