Fancy a trip down a wormhole? We have never been quite sure whether these portals through space-time could exist long enough for anything to travel through. Now calculations suggest they could stick around for a while - perhaps as long as the universe itself.

In 2011, a study led by economist Donna Ginther of the University of Kansas in Lawrence found that black applicants were significantly less likely than white applicants to be funded by the National Institutes of Health (NIH). Since then, NIH officials have examined a host of factors that might cause the disparity, from the historical advantages that white men enjoy to overt discrimination by grant reviewers. But the picture remains cloudy.

Saturn has overtaken Jupiter as the solar system's satellite king. Astronomers just discovered 20 previously unknown Saturn moons, boosting the ringed planet's tally of known satellites to 82 — three more than Jupiter. And there's more exciting news: You can help name these newfound objects.

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the centre of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the Galaxy and out into deep space.

Unlike the robotic explorers now prowling Mars’ dusty landscapes, these new craft -- launched by both NASA and a European-Russian collaboration -- will be engaged in a type of reconnaissance that hasn’t been tried since NASA’s Viking landers set down there in the mid-1970s. The new craft will go beyond merely scouting for locations that were once suitable for life. They’ll be on the hunt for life itself. Dead or alive.

More than six months after canceling what would have been the first spacewalk conducted by a team of two women, NASA has rescheduled the historic moment for Oct. 21. The spacewalk will be conducted by NASA astronauts Christina Koch, who has been living in space since March and was scheduled for the original all-women spacewalk, and Jessica Meir, who arrived at the International Space Station in September.

Since the availability of material is key to star formation in a galaxy, knowing the rate at which it is added and lost is important to understanding how galaxies evolve over time. And as Michael Foley of Astrobites summarized, characterizing the rates at which material is added to galaxies is crucial to understanding the details of this "galactic fountain" model.

Amazon CEO Jeff Bezos’ Blue Origin space venture has always shied away from saying how much it will cost to fly to the edge of the final frontier on its New Shepard suborbital spaceship. But today, Blue Origin CEO Bob Smith hinted at a ballpark figure.

It was just this year that we got our first real look at a black hole, and it matched many of the theoretical predictions that came before the Event Horizon Telescope (EHT) project made history. An impressive new NASA simulation shows us what that black hole might look like if we were closer.

GJ 3512 b is a gas giant orbiting a tiny red dwarf, GJ 3512. The planet itself is in an eccentric, 204-day orbit around its star, but spends most of its time closer to its parent than Mercury is to Sol. GJ 3512, however, can only manage ~0.2 percent of our Sun’s solar output. But a planet the size of GJ 3512 b isn’t supposed to exist.
