According to multiple lines of evidence, Venus was once a much different planet than it is today. But roughly 500 million years ago, a massive resurfacing event triggered a runaway greenhouse effect that led to the hot, poisonous, and hellish environment we see there today. Therefore, the study of Venus presents an opportunity to model the evolution of planetary environments, which can serve as a reference for what could happen in the future.
Japanese billionaire Yusaku Maezawa and two crewmates have returned to Earth after an 11-day mission to the International Space Station that was marked by online innovations including an NFT drop and a lottery giveaway.
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll feel a little odd after today’s topic: irregular galaxies!
The dream of building a permanent settlement on the Moon: a place where humans from all walks of life can come together and give rise to a new culture and identity. A place where vital scientific research and experiments can be conducted, lunar industries created, and people can go for a little “adventure tourism.” It’s been the stuff of science fiction and speculative literature for over a century. But in the coming years, it could very well become a reality.

What causes an otherwise unremarkable star to become over 100 times brighter? That’s a question astronomers have been pondering since 1936, when a star in Orion brightened from 16th magnitude to 8th magnitude in a single year.
Thanks to the explosion in discoveries made in the last decade, the study of extrasolar planets have entered a new phase. With 4,884 confirmed discoveries in 3,659 systems (and another 7,958 candidates awaiting confirmation), scientists are shifting their focus from discovery to characterization. This means examining known exoplanets more closely to determine if they possess the necessary conditions for life, as well as “biomarkers” that could indicate the presence of life.

December 17 is an historic day for flying machines, so it wouldn’t be surprising if we hear the Ingenuity Mars Helicopter makes an attempt at its 18th flight sometime today. In case you need a little reminder, on this day in 1903, the Wright Brothers had their first successful flight, flying their plane for exactly 120 feet over 12 seconds.
Outer space is a great place to go if you want to study the Earth. Although outward-looking spacecraft like Hubble and the highly anticipated James Webb Space Telescope garner most of the attention from the public – understandably, given their spectacular imagery of distant astronomical phenomena – the large majority of satellite infrastructure in orbit is actually focused back on our home planet. The unparalleled view of the planet from space offers unique advantages to scientists hoping to measure changes and patterns here on Earth that just aren’t possible from the ground. In 2022, NASA will launch four new Earth science missions, each offering something unique, and adding a new way to understand, and protect, our home.

For the first time ever, a spacecraft has flown through the Sun’s outer atmosphere. The Parker Solar Probe passed through the out portion of the Sun’s corona in April of 2021, passing directly through streamers of solar plasma.

For literally being black in the truest sense of the word, black holes are surprisingly easy to spot. Astronomers have spent decades at this point purposely searching for them and have found thousands already, with potentially 100 billion existing in our part of the universe. We are still finding new types and configurations of black holes consistently. Now, new research led by Dr. Karina Voggel of the Strasbourg Observatory found a pair of black holes that hold the new records of being both the closest supermassive black hole pair to Earth and the closest together pair ever seen.
In the search for “potentially-habitable” extrasolar planets, one of the main things scientists look at is stellar activity. Whereas stars like our own, a G-type (G2V) yellow dwarf, are considered stable over time, other classes are variable and prone to flare-ups – particularly M-type red dwarf stars. Even if a star has multiple planets orbiting within its habitable zone (HZ), the tendency to periodically flare could render these planets completely uninhabitable.

During the night of December 10, 2021, severe weather tore through several US states, Arkansas, Illinois, Kentucky, Mississippi, Missouri and Tennessee. At least 70 tornado-like events were reported, and one storm cell was tracked on radar for approximately four hours as it traveled for more than 400 km (250 miles.)
