Days after millions of young people took to the streets around the globe to protest for more aggressive action on climate change, dozens of world leaders arrived Monday at the United Nations facing a simple question: What's your plan?

The verdict is in: after a thorough round of observations, the comet suspected of being an interstellar alien has been ratified. According to the International Astronomical Union (IAU), the comet is "unambiguously" interstellar in origin, and it ha

It's hard living in a relativistic Universe, where even the nearest stars are so far away and the speed of light is absolute. It is little wonder then why science fiction franchises routinely employ FTL (faster-than-light) as a plot device.

For all our perception of supermassive black holes as gravitational vortices ravenously devouring stars, it doesn't actually happen that often. For instance, our galaxy's own black hole might only do it a handful of times every 100,000 years.

SpaceX CEO Elon Musk has revealed updated renders of conceptual Moon and Mars bases that may ultimately be made possible by the company’s next-generation Starship and Super Heavy launch vehicle. With Starship, SpaceX hopes to enable the rapid and affordable…

Speaking on Saturday night (Sept. 28th) at the base of the SpaceX’s Starship Mk1 prototype in Boca Chica, Texas, CEO Elon Musk delivered an update on the progress the company is making with Starship and its Super Heavy booster, including the first renders…

At the edge of our Solar System, some unknown object is manipulating the paths of chunks of ice as they circle the Sun.

Widespread antibiotic use is largely to blame for the emergence of antibiotic resistant bacteria, which is currently one of the biggest threats to global health. Not only does antibiotic resistance already cause an estimated 700,000 deaths a year,

There's something almost mythical in a perfect steak. While it seems like a very simple thing to do - throw a bit of meat on the grill, cook until done - there's an art to getting steak right that takes the humble hunk of cow from a boring dish int

According to a decade-long study by an international team of researchers, human CO2 emissions total 100 times more than the planet-warming effects of all volcanoes combined.

Our next-door neighbour is a cannibal. In its distant past, the Andromeda galaxy has devoured at least two other galaxies, subsuming their stars into its galactic halo. And now, for the first time, astronomers have identified those stars, tracking

Scientists just found the most basic ingredients for life bursting from an ocean on Saturn's moon Enceladus.

After counting all the normal, luminous matter in the obvious places of the universe – galaxies, clusters of galaxies and the intergalactic medium – about half of it is still missing. So not only is 85 percent of the matter in the universe made

In a death-defying maneuver for the spacecraft, NASA's Juno has completed an unprecedented and unplanned engine burn. The purpose? To save the spacecraft's 'life', or at least the rest of its mission to Jupiter.

Research suggests there could be a good scientific reason why some of us struggle to look someone in the eye and hold a conversation with them.

Saturn has unseated Jupiter as the Solar System's most moon-bearing planet, the Carnegie Institution for Science announced on Monday.

A cosmologist who revealed that the universe was made mostly of invisible matter and energy, and two scientists who detected the first planet orbiting an alien star, were jointly awarded the 2019 Nobel Prize in physics Tuesday.

A drug that's currently in development for treating leukemia has delivered a surprise in mouse studies by reversing a previously untreatable symptom of schizophrenia - the impairment of spatial working memory.

NASA astronomers have used data from the Voyager probes to measure the bustle of particles rippling at the very edge of our Solar System, and discovered the pressure in the distant borderlands of our star is higher than they expected.
