This is Northrop Grumman’s grand vision for a new NASA Space Station

The International Space Station (ISS) is aging and has been developing issues that could one day make it uninhabitable over the last several years. After spending decades in orbit, NASA looks to a future where other space stations will also orbit the Earth. Rather than being developed by NASA and partner nations, these future space stations will be commercial projects. NASA has awarded a contract to Northrop Grumman to develop a cost-effective commercial free-flying space station in low Earth orbit (LEO).

NASA reveals the 3 contenders to replace the International Space Station

NASA reveals the 3 contenders to replace the International Space Station

While the International Space Station is the destination for conducting research in low-Earth orbit, it will not be that way forever. The United States and NASA, along with partners worldwide who are already helping to maintain the ISS, will continue to fund the space station for a few more years, but eventually, it will have to be replaced. NASA has now named three companies selected to submit designs for new space stations, and there are some familiar names on the list.

NASA’s TESS found a boiling exoplanet with an 8 hour year

NASA’s TESS found a boiling exoplanet with an 8 hour year

NASA's TESS (Transiting Exoplanet Survey Satellite) performs the job of discovering distant planets orbiting other stars extremely well. It has discovered thousands of potential exoplanet candidates, and a number of those have been confirmed to be planets orbiting distant stars. In its latest discovery, TESS has found an exoplanet the size of Mars but similar to the composition of Mercury.

What Are Black Holes and How Do They Form?

What Are Black Holes and How Do They Form?

You've probably heard of black holes existing in the universe and may even have studied the phenomena in a high school science class. According to NASA, scientists speculate that they can range in size from a mere atom to supermassive ones the size of a million suns combined.

While countless artists have used their imaginations to depict these mysterious objects, you might be surprised to find out that, in spite of the size of some of them, they cannot be seen with either the naked eye or with the most powerful telescopes. How can something potentially so massive hide so well? To understand this, we must learn about what black holes are and how they are formed.

Who Invented the Space Suit?

Who Invented the Space Suit?

Before humankind was able to explore the sky outside of Earth's orbit, we first had to get an understanding of what happens to our bodies once we ascend past a certain elevation. Fly too high in the sky and the human body will succumb to a lack of oxygen. And if you survive that, the colder atmosphere will surely lead to hypothermia. Believe it or not, it took the perseverance of one determined Spaniard to figure out how to work around those issues, allowing for exploring the skies at great heights.

The 11 Most Influential Women in NASA History

The 11 Most Influential Women in NASA History

The history of the United States space program was molded in part by the many women who have not only been launched into orbit aboard spacecraft, but who have also worked tirelessly behind the scenes in making the rocket and shuttle launches mathematically possible. From the more than 50 women launched into space, to the engineers that started the process on paper, women have been an integral part of NASA from the beginning (via History of NASA).

This Stanford drone has bird legs for perching

This Stanford drone has bird legs for perching

Engineers at Stanford University have been working on a robot that is part quadrotor flying drone and part peregrine falcon. The upper half of the robot looks like a common quadrotor drone designed to fly through the air. The lower half of the drone has a pair of clawed feet - significantly different from anything we've seen in the past.

This man has the world’s first 3D printed eye

There are a variety of injuries and disease conditions that can result in the loss of an eye. Often, prosthetic eyes are made of glass painted to look like a natural eyeball. However, in the future prosthetic eye replacements will be made by 3D printers. Researchers at Fraunhofer Technology have made breakthroughs in 3D printing prosthetic eyes and have supplied their 3D printed eye to the first patient.

Google’s quantum processors take stable time crystals beyond just theory

Google’s quantum processors take stable time crystals beyond just theory

Time crystals are back in the news, and not the ones from TimeSplitters. A study recently published in Nature builds upon previous research released earlier this year on time crystals, a new phase of matter that holds significant promise for the future of quantum computing. This time around, the researchers say Google's Sycamore quantum hardware was used to observe a stable time crystal.

Very Large Telescope spots Earth’s new nearest pair of black holes

Very Large Telescope spots Earth’s new nearest pair of black holes

Astronomers with the European Southern Observatory (ESO) use the Very Large Telescope (VLT) to scan the heavens in search of stars, black holes, galaxies, and planets to study. Recently, astronomers used the VLT to spot the closest pair of supermassive black holes to Earth ever discovered. Eventually, the black hole duo will merge into a single gigantic black hole. The discovery is located in a galaxy called NGC 7727, which lies in the constellation Aquarius.

Ultrahot Jupiter exoplanet orbits its star in 16 hours

Ultrahot Jupiter exoplanet orbits its star in 16 hours

We all know that it takes the Earth 365 days to orbit the Sun, marking an entire year. In our solar system, a year on other planets varies greatly depending on how close they are to our star. Mercury, which is both the smallest planet and the closest planet to the sun, takes 88 days to orbit the star. By comparison, dwarf planet Pluto takes 248 years to orbit the Sun. MIT astronomers have discovered an exoplanet described as an ultrahot Jupiter that orbits much more quickly and much closer to its host star than Mercury.

Scientists use AI to design self-replicating xenobots from frog cells

Scientists use AI to design self-replicating xenobots from frog cells

Last year, a team of scientists announced the development of "living robots," a new type of organism made using cells harvested from frog embryos. That same team is back with an update on these "robots," which they call xenobots, detailing a new scientific milestone: the ability to self replicate using existing cells.
