In the last year, Betelgeuse has experienced two episodes of dimming. Normally, it’s one of the ten brightest stars in the sky, and astrophysicists and astronomers got busy trying to understand what was happening with the red supergiant. Different research came up with some possible answers: Enormous starspots, a build-up of dust, pre-supernova convulsions.
It’s been over a thousand days since the historic kilonova observation, and yet the region continues to emit X-rays, long after models predicted they should have faded away.
January 31, 2021, will mark 50 years since the launch of Apollo 14.
NASA and Seven Countries Sign the Artemis Accords for the Exploration of the Moon. Russia Declined to Participate
It looks like Russia is thumbing its nose at international cooperation on the Moon. They’ve refused to sign the Artemis Accords, which are a set of rules governing Lunar exploration.
The dwarf galaxy known as Dragonfly 44 caused a stir recently: apparently it had way, way more dark matter than any other galaxy. Since this couldn’t be explained by our models of galaxy formation, it seemed like an oddball.
NASA recently awarded contracts to fourteen companies to develop technologies that will help them return to the Moon, and stay there! The post NASA Announces 14 New “Tipping Point” Technologies for its Lunar Exploration appeared first on Universe Today .
We actually don’t know how fast the Milky Way’s supermassive black hole is spinning but there might be a way to find out
The stars at the center of our galaxy could tell us just how fast our closest supermassive black hole is spinning. The post We actually don’t know how fast the Milky Way’s supermassive black hole is spinning but there might be a way to find out appeared first on Universe Today .
A new study found that warmer ocean temperatures driven by climate change have caused Australia’s Great Barrier Reef to lose more than half of its corals since 1995. The researchers say virtually all coral populations along the Great Barrier Reef have declined due to repeated “bleaching events” in the past 25 years.
Fusion power is the technology that is thirty years away, and always will be – according to skeptics at least. Despite its difficult transition into a reliable power source, the nuclear reactions that power the sun have a wide variety of uses in other fields. The most obvious is in weapons, where hydrogen bombs are … Continue reading “Impatient? A Spacecraft Could Get to Titan in Only 2 Years Using a Direct Fusion Drive” The post Impatient?

It’s been a long road for InSight’s Mole. InSight landed on Mars almost two years ago, in November 2018.
There are instances other than pandemics when it is necessary to work remotely.
We can thank NASA’s New Horizons spacecraft for opening our eyes up to Pluto’s complexity.
Just like Earth, Mars undergoes seasonal changes due to its axial tilt. And while summer heat on Mars can’t compare with Earth’s, along with the Martian summer warmth comes an increase in small whirling storms known as dust devils. Several spacecraft on or orbiting Mars have captured dust devils in action, including the Phoenix lander … Continue reading “Summer is Dust Devil Time on Mars” The post Summer is Dust Devil Time on Mars appeared first on Universe Today
The SN8 Starship prototype just got its three Raptor engines, and is now preparing to test fire them. After that, it’s smooth sailing towards the 15 km (50,000 ft) hop test! The post Elon Musk Shares a View of Starship With Three Raptor Engines Installed appeared first on Universe Today .
Does it feel like all eyes are on Venus these days? The discovery of the potential biomarker phosphine in the planet’s upper atmosphere last month garnered a lot of attention, as it should.
The CNSA (Chinese National Space Agency) has released an image of its Tianwen-1 spacecraft to coincide with the National Day and Mid-Autumn Festival. The spacecraft is on its way to Mars, and if the landing is successful, China will be only the third nation to successfully land a spacecraft on the planet. The image shows … Continue reading “China’s Mars-bound Tianwen-1 Takes a Selfie” The post China’s Mars-bound Tianwen-1 Takes a Selfie appeared first on Universe Today
