SpaceX's rocket fairing-catching boat Mr. Steven just got a major upgrade

The new net is about 4 times the size of the previous one and is nearly an acre in size. The ship is classified as a "fast supply vessel" one that is rated to carry about 400 tonnes of cargo at speeds that exceed 43 kmh.

Pluto is in alignment with Earth and Sun for the first time in nearly 100 years

Pluto is almost always either above the rest of the planets or below, depending on where it is in its long orbit. Only twice every Plutonian year will the planet line up with the rest of the Solar System.

South Pole observatory detects neutrino from supermassive black hole from another galaxy for the first time

This particular neutrino has been travelling about 3.7 billion years at nearly the speed of light before scientists found it passing through Earth and crashing into Antarctic ice.

At 200 db, these rockets are so loud that they can rip off rainbows in the sky (VIDEO)

At 200 decibels, the noise levels are about 80 decibels more than the average pain threshold. Apart from the immense heat that launches generate, the rumbling sound alone is enough to not only hurt people, it can literally set hair on fire and even topple buildings.

How fast is the universe expanding? Gravitational waves give us a hint

Researchers believe knowing how fast the universe is expanding could shed light on the origins of the existence as well as describe whether the cosmos is ultimately headed for collapse or indefinite expansion.

Watch NASA demolish two rocket launch towers using explosives

This is the same complex where Opportunity, Spirit, and all the Pioneer missions were launched. It was active from the 1950s all the way to 2011.

NASA might have found, destroyed complex organic material on Mars 40 years ago

Complex organic material is the closest pointer to actual life outside the Earth. We now know that they exist on Mars, but this discovery could have come 40 years back.

How big are SpaceX rockets? This visual helps you see just how massive these machines are

One of the reasons why it is not easy to visualise the size and magnitude of these machines is because of the way they are presented. Launch pads are isolated, normally near the coast, and there is nothing near them except for the sky and a launch tower for scale comparison.
