Behind the lens at SpaceX’s historic Falcon Heavy launch

Take a peek into the launch day notebook of a pro rocket photographer for a few tips.

Temperatures at the North Pole are about to reach or possibly exceed the freezing point this week as the North Atlantic and the North Pacific Oceans inject unusually mild air into the Arctic. Not coincidentally, Arctic sea ice is at record low levels. ... See more

The polar vortex split, and now the North Pole is comparatively balmy.

The biggest black holes in the Universe are growing faster than the rate of stars being formed in their galaxies, according to two new studies using data from NASA’s Chandra X-ray Observatory and other telescopes. ... See more

Scientists listening out for broadcasts by extra-terrestrials are struggling to get the computer hardware they need, thanks to the crypto-currency mining craze.

A scientist says the search for alien intelligence has been hit by a shortage of computer hardware.

New Horizons, the first NASA spacecraft to fly by Pluto, is still making history as it cruises deeper into the distant edges of the Solar System. Late last year, the little probe used one of its cameras to take a picture of a galactic star cluster — officially snapping the most distant picture from Earth ever made. ... See more

Breaking Voyager 1’s record

The SpaceX Falcon Heavy launch was remarkably successful. But what do you think of the Tesla car now in orbit around the Earth?

Elon Musk's most powerful rocket so far is finally ready for launch. The Falcon Heavy spacecraft is scheduled to take off from its Cape Canaveral, Florida, launchpad on February 6. The launch comes after the Federal Aviation Authority approved SpaceX's application for a licence. It is SpaceX's most ambitious but also riskiest launch so far. ... See more

Elon Musk dreams of creating a million-person city on Mars. But first, the SpaceX and Tesla founder is going to need a small group of people with an unusual genetic trait in common; resistance to radiation.

Radiation resistance in humans and animals is something we know little about, although we know it exists. At the moment, resistance tests are used to try and predict how much radiation cancer patients can survive, but one day this could be an important decider of who gets to venture into space.

Our Earth is protected from the harmful radiation from the Sun by our magnetic field, but astronauts that leave the planet will be bombarded with the dangerous particles. ... See more

People who live on Mars may need to be genetically altered to be resistant to radiation. And while it might seem a long way off, research is already underway to work out how this can be done
