NASA platform used to launch Apollo 11 to the moon set for demolition
NASA's Mobile Launch Platform-3, from which the first astronauts departed Earth to fly around and land on the moon now, itself, only has a limited time left on the planet.
The 1st photo of Earth from Europe's powerful new satellite is amazing
Europe's newest weather satellite has snapped an image of the Earth from space, revealing our planet in incredible detail.
Chasms on the flanks of a martian volcano
Mars has some of the most impressive volcanoes in the Solar System. ESA’s Mars Express has now imaged the pitted, fissured flank of the planet’s second-tallest: Ascraeus Mons.
Chasing SpaceX: The Commercial Space Race Gets a Reality Check
Can anyone keep up with SpaceX in the commercial space race?
We Can Only Bring 30 Samples of Mars Back to Earth. How Do We Decide?
The Mars Sample Return Mission is one of the most ambitious missions ever conceived. Though the samples won’t be returned to Earth until 2033 at the earliest, the Perseverance Rover is busy collecting them right now. Ideally, Perseverance could gather as many samples as we like and ship them all back to Earth. But of course, that’s not possible.
Powerful sun storm could supercharge auroras this week
The sun fired a huge cloud of plasma directly at Earth on Sunday evening (May 7), an outburst that could boost auroras in the next day or so.
The moon's heart of iron revealed for the 1st time
New research has revealed the heart of the moon as never seen before, demonstrating that it has a solid core that is composed of iron like Earth.
Titan
Titan is the largest moon of Saturn and the second-largest moon in the Solar System. It is a fascinating world with a dense atmosphere, liquid methane and ethane lakes, and a diverse landscape that includes mountains, valleys, and sand dunes.
Chinese startup aims to debut new reusable rocket next year
The Chinese launch startup Galactic Energy is making moves toward launching Pallas 1, its small Falcon 9-like rocket.
What Does the Milky Way Look Like?
Beginning in 1610, when famed Renaissance polymath Galileo Galilei observed the night sky using a telescope of his own manufacture, astronomers gradually realized that our Solar System is part of a vast collection of stars known today as the Milky Way Galaxy. By the 20th century, astronomers had a good idea of its size and structure, which consisted of a central “bulge” surrounded by an extended disk with spiral arms. Despite all we’ve learned, determining the true morphology of the Milky Way has remained a challenge for astronomers.
James Webb Space Telescope snaps amazing photo of alien asteroid belt
The first asteroid belt ever found outside the solar system is more complex than expected, new observations by the James Webb Space Telescope reveal.
Look for 'Earthgrazers' as the Eta Aquarid meteor shower overlaps the new moon on May 19
The peak of the Eta Aquarid meteor shower unfortunately coincided with a bright full moon, but there is still time to catch a few stragglers was we approach the new moon on May 19.
JWST Fails to Disprove the Big Bang
The James Webb Space Telescope (JWST) is revolutionizing our understanding of the early universe. With a mirror larger than Hubble and the ability to observe deep into the infrared, JWST is giving us a detailed view of that period of the universe when galaxies were just starting to form. The results have been surprising, leading some to argue that they disprove the big bang. But the big bang is still intact, as a recent study shows.
China's mysterious space plane returns to Earth after 9-month orbital mission
China's mysterious space plane landed on Monday (May 8), bringing its second orbital mission to an end after 276 days.
LISA Will Be a Remarkable Gravitational-Wave Observatory. But There’s a Way to Make it 100 Times More Powerful
The first-time detection of Gravitational Waves (GW) by researchers at the Laser Interferometer Gravitational-wave Observatory (LIGO) in 2015 triggered a revolution in astronomy. This phenomenon consists of ripples in spacetime caused by the merger of massive objects and was predicted a century prior by Einstein’s Theory of General Relativity. In the coming years, this burgeoning field will advance considerably thanks to the introduction of next-generation observatories, like the Laser Interferometer Space Antenna (LISA).
Astronomers Watch a Star Gulp Down One of its Planets
A star like our Sun only shines the way it does because of its intrinsic balance. Stars are massive, and the inward gravitational pressure from all that mass acts to contain the outward thermal pressure from all the fusion inside the star. They are in equilibrium, or on the main sequence if you like, and the result is a spherical mass of plasma that holds its shape and emits radiation with relative stability for billions of years. Like our Sun.
The James Webb Space Telescope Reveals Fomalhaut's Disk In Unprecedented Detail
Continuing its run of ground-breaking discoveries, the James Webb Space Telescope has snapped the clearest images yet of the dusty disk around the young star Fomalhaut.
See bright Venus climb to its highest point in the night sky tonight
Venus is quite bright as it climbs high in the night sky on Monday (May 8) during its current period of evening appearances.
Virgin Galactic targeting late May for last test flight before opening for space tourism
Virgin Galactic plans to launch its fifth spaceflight late this month, a test that aims to pave the way for the start of commercial service next month.
Webb looks for Fomalhaut’s asteroid belt and finds much more
Astronomers used the NASA/ESA/CSA James Webb Space Telescope to image the warm dust around a nearby young star, Fomalhaut, in order to study the first asteroid belt ever seen outside of our Solar System in infrared light. But to their surprise, they found that the dusty structures are much more complex than the asteroid and Kuiper dust belts of our Solar System.
