Once the Saints game is over Sunday night, you can experience yet another phenomenon that is out of this world.

A scientist at NASA animated how long it takes light to travel around Earth, to the moon, and to Mars. The movies show just how slow light can be.

One of the last acts of NASA's Cassini spacecraft before its death plunge into Saturn's hydrogen and helium atmosphere was to coast between the planet and its rings and let them tug it around, essentially acting as a gravity probe. Precise measurements of Cassini's final trajectory have now allowed scientists to make the first accurate estimate of the amount of material in the planet's rings, weighing them based on the strength of their gravitational pull.

Today, astronomers have numerous extrasolar systems to study, but most look very different from our own. Determining how these solar systems — and ours — formed is challenging. New research presented at the 233rd Meeting of the American Astronomical Society in Seattle, Washington, on January 8 lends credence to an idea that goes against previous thoughts about planet formation, but has been gaining traction in the field...

The seeds, inside a sealed container, are the first plants ever grown on the Moon's surface.

For the first time, a new network of satellites will soon be able to track all commercial airplanes in real time, anywhere on the planet. Currently, planes are largely tracked by radar on the ground, which doesn't work over much of the world's oceans. The final 10 satellites were launched Friday to wrap up the $3 billion effort to replace 66 aging communication satellites, reports CBS News' Kris Van Cleave, who got an early look at the new technology.

The head of Harvard University's Astronomy Department is doubling down on his claim from November 2018 that the space rock Oumuamua, the first interstellar object to enter our solar system, which it did in 2017, was an alien probe. Dr. Avi Loeb was interviewed by Haaretz about his controversial claim, which was made in a paper published in the Astrophysical Journal Letters. Co-author and Harvard astrophysicist Shmuel Bialy had stated, “Currently there is an unexplained phenomena, namely, the excess acceleration of Oumuamua...

China’s miniature biosphere experiment has yielded sprouting cotton seeds, and they are the first plants to germinate on the Moon—an important first step in creating a viable, self-sustaining lunar colony. China’s Chang’e 4 lander arrived on the Moon’s far side on January 3, 2018. Among its cargo is a miniature lunar biosphere developed by scientists at Chongqing University. This experiment consists of a 7-inch-long, airtight container filled with soil, air, water, various seeds, yeast, and fruit fly eggs.

On October 19, 2017, astronomers at the University of Hawaii spotted a strange object travelling through our solar system, which they later described as “a red and extremely elongated asteroid.” It was the first interstellar object to be detected within our solar system; the scientists named it ‘Oumuamua, the Hawaiian word for a scout or messenger. The following October, Avi Loeb, the chair of Harvard’s astronomy department, co-wrote a paper (with a Harvard postdoctoral fellow, Shmuel Bialy) that examined ‘Oumuamua’s “peculiar acceleration” and suggested that the object...

Scientists want to return to Saturn's moon Titan to investigate its complex chemistry — this time buoyed by Earth's fascination with drone technology.

NASA astronaut David Scott, the seventh person to walk on the Moon and, funnily enough, the first to drive around on it, is one of four people still left alive that can describe such an experience. Per BBC, he said that he’s often asked about what it was like. “I describe the majesty of the lunar mountains, the layers of volcanic lava or the beauty of the sparkling crystals in the rocks,” he wrote in his book, Two Sides of the Moon. “Only an artist or poet could convey the true beauty of space.”

In the 2015 blockbuster The Martian, Matt Damon plays an astronaut who gets stranded on Mars and survives by growing potatoes, producing enough food to last months. China’s lunar mission could bring that piece of science fiction a step closer to reality if it succeeds in growing the first flower on the moon in less than a hundred days’ time, an experiment that the China National Space Administration said it would soon broadcast.

Moving to protect the U.S. from advanced missile threats from China and Russia, President Donald Trump on Thursday laid out plans for a new array of space-based sensors and other high-tech systems designed to more quickly detect and defeat attacks. Trump, in a speech at the Pentagon, declared that space is the new warfighting domain. And he vowed that the U.S. will develop an unrivaled missile defense system to protect against advanced hypersonic and cruise missile threats from competitors and adversaries.

Cheap, sun-reflecting satellites could kickstart space advertising — the satellite equivalent of planes towing banners. Astronomers say it's light pollution.

The U.S. government may be in partial shutdown mode, but operations to configure instruments critical to NASA’s InSight mission on Mars are right on schedule—and things are going swimmingly, as the latest mission update attests. Our last update from the InSight mission came on December 20 following the probe’s successful deployment of the SEIS instrument, or Seismic Experiment for Interior Structure, onto the Martian surface. The configuration of this hexagonal-shaped device is still ongoing, but an update from the SEIS team shows things are proceeding as planned.

Late in 2018, the gravitational wave observatory, LIGO, announced that they had detected the most distant and massive source of ripples of spacetime ever monitored: Waves triggered by pairs of black holes colliding in deep space. Only since 2015 have we been able to observe these invisible astronomical bodies, which can be detected only by their gravitational attraction.

Models and observations indicate that both stars and planets form as a cloud of material collapses into a disk. If the process proceeds in an orderly manner, then the planets will all form from the same disk and thus orbit in the same plane. And—because material from the same disk will fall into the star, bringing its momentum with it—the star will rotate with its equator along the same plane. That should lead to a tidy system with the equator of the star lined up with the plane of any planets orbiting it.

Given that the half-century-old technology embodied in Voyager 1 and 2 recently traversed the boundary between the solar wind and the interstellar medium, it is likely that within the next century our civilization will exit the solar system boundary, marked by the Oort cloud, a thousand times farther away. Venturing into interstellar space will signal our transition from a sun-based residence to the grander neighborhood of other stars in the Milky Way galaxy.

The universe is far from homogenous. Rather, stars, and the galaxies that contain them, clump together in some places, brought together by their shared gravitational attraction. Astronomers have historically found clusters of galaxies in the sky to be relatively easy to spot, as they’re extremely large and bright. But one new study suggests that a third of all galaxy clusters have been hiding undiscovered out in the cosmos.

The budding cotton seed hailed as the first plant to ever grow on the Moon, has, erm, died. Xinhua, China’s state owned press agency, announced the unfortunate news merely hours after celebrating the plant’s successful germination. “The experiment has ended,” it said. Maybe it's not that surprising, considering, the picture of the plant tweeted by the People's Daily, the official newspaper of China's Communist Party, was very difficult to spot.

Astronomers may have discovered a new way that stars can die. A mysteriously brief and bright burst whimsically called the “Cow” reveals an entirely new type of stellar death. The details of that stellar doom, however, remain hazy. Scientists are still debating whether the flare-up, spotted on June 16, 2018, was from an unusual type of star that was eaten by a black hole, or from an old, massive star exploding in a weird sort of supernova.

The appearance of a single green leaf hinted at a future in which astronauts would grow their own food in space, potentially setting up residence at outposts on the moon or other planets. Now, barely after it had sprouted, the cotton plant onboard China’s lunar rover has died. The plant relied on sunlight at the moon’s surface, but as night arrived at the lunar far side and temperatures plunged as low as -170C, its short life came to an end.

It shines with a brightness equivalent to 600 trillion suns. “We don’t expect to find many quasars brighter than that in the whole observable universe,” said the astronomers. Researchers announced this week (January 9, 2019) at the 233rd meeting of the American Astronomical Society in Seattle, Washington, that they’ve discovered the brightest quasar yet known, detected from the period when the universe was just beginning to make luminous objects, such as stars and galaxies.

Hubble, the trusty space telescope that has been delivering gorgeous views of the cosmos for decades now, just delivered another gift. In a new composite image made up of many individual photos, Hubble shows us the nearby Triangulum galaxy in incredible detail. No, seriously, the final image is so huge that you’d never want to wait for it to load on a web page.

One of the most cherished science fiction scenarios is using a black hole as a portal to another dimension or time or universe. That fantasy may be closer to reality than previously imagined. Black holes are perhaps the most mysterious objects in the universe. They are the consequence of gravity crushing a dying star without limit, leading to the formation of a true singularity – which happens when an entire star gets compressed down to a single point yielding an object with infinite density.

Using data from NASA's Kepler space telescope, citizen scientists have discovered a planet roughly twice the size of Earth located within its star's habitable zone, the range of orbital distances where liquid water may exist on the planet's surface. The new world, known as K2-288Bb, could be rocky or could be a gas-rich planet similar to Neptune. Its size is rare among exoplanets - planets beyond our solar system.

The Hubble Space Telescope's mind-blowing new image of the Triangulum Galaxy is almost as gigantic as the galaxy itself. Triangulum, also called Messier 33, can be spotted by lucky skywatchers without an assist from a telescope, but it looks like a smudge. Hubble's vivid view combines 54 images into one image showing the central part of the galaxy and some of its spiral arms.

Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada. The precise nature and origin of the blasts of radio waves is unknown. Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away.

There once was a miniature garden growing on the far side of the moon. The China National Space Agency's Chang'e 4 lander is exploring the mysterious side of our lunar neighbor that faces away from Earth. It also had some unusual guests on board and -- in a first for the moon -- one of them sprouted. Xinhua announced the sprout Tuesday and posted a series of progress images covering the course of nine days and showing a seedling reaching up inside the habitat. The experiment didn't last long. The same day, China's state-run Xinhua News declared that it's already ended.

"Starship will look like liquid silver."

Come one, come all and behold the future of space travel: steam power! No, seriously; half a century after the world's first manned space mission, it seems that interplanetary travel has finally entered the steam age. Scientists at the University of Central Florida (UCF) have teamed up with Honeybee Robotics, a private space and mining tech company based in California, to develop a small, steam-powered spacecraft capable of sucking its fuel right out of the asteroids, planets and moons it's exploring.

In a first for the world, the Chinese National Space Agency successfully landed a spacecraft on the far side of the moon Thursday, a state broadcaster reported. The probe, named Chang’e 4, launched in early December — the latest in a series of missions aimed at exploring the moon and paving the way for Chinese astronauts to eventually land on the lunar surface. The country plans to launch a sample return mission to the moon later this year.

Scientists from Russia and around the world see plasma rocket technology as a crucial possible ingredient for speedy missions to Mars and beyond. Physicists from the Budker Institute of Nuclear Physics of the Siberian branch of the Russian Academy of Sciences in Novosibirsk are preparing another round of experiments aimed at successfully harnessing the power of thermonuclear plasma for use in a rocket engine, institute deputy director Alexander Ivanov has told journalists.

Fresh greens in space? Recent research has looked into how plants respond to low levels of gravity and a particular hormone which can help plants grow in challenging space conditions. Now, new research has succeeded in growing plants in high-tech planters which use artificial soil made from lava rock.
