SpaceX on Thursday announced a partnership to send three tourists to the International Space Station (ISS), the first private trip in more than a decade.

Elon Musk’s company has signed a deal with Axiom Space to transport the tourists along with a commander on one of its Crew Dragon capsules in the second half of 2021.

Axiom CEO Michael Suffredini said the flight “will represent a watershed moment in the march toward universal and routine access to space.” He did not reveal a price tag.

The cost of launching a SpaceX Falcon 9 rocket is around $60 million and, throwing in the cost attached to building a new capsu...

Organic compounds called thiophenes are found on Earth in coal, crude oil and oddly enough, in white truffles, the mushroom beloved by epicureans and wild pigs.

Thiophenes were also recently discovered on Mars, and Washington State University astrobiologist Dirk Schulze-Makuch thinks their presence would be consistent with the presence of early life on Mars.

Schulze-Makuch and Jacob Heinz with the Technische Universität in Berlin explore some of the possible pathways for thiophenes’ origins on the red planet in a new paper published in the journal Astrobiology. Their work suggests that a biological process, most likely involving bacteria rather than a truffle though, may have played a role in the organic compound’s existence in the Martian soil.

The Earth of 3.2 billion years ago was a “water world” of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean crust that’s now exposed on land in Australia.

And that could have major implications on the origin of life...

Scientists have identified a sub-atomic particle that could have formed the ‘dark matter’ in the Universe during the Big Bang. Nuclear physicists are putting forward a new candidate for dark matter – a particle they recently discovered called the d-star hexaquark.

Up to 80% of the Universe could be dark matter, but despite many decades of study, its physical origin has remained an enigma. While it cannot be seen directly, scientists know it exists because of its interaction via gravity with visible matter like stars and planets. Dark matter is composed of particles that do not absorb, reflect or emit light.

Now, nuclear physicists at the University of York are p...
