Citizen Science Month is built around a goal of 2.5 million 'Acts of Science,' tying the annual event to America's 250th birthday through a simple but powerful idea: lots of small contributions can add up to something really meaningful.
The South Pole Observatory peers into the vastness of the Universe to address one of its most compelling questions: what happened immediately after the Big Bang? Exploiting uniquely favorable observing conditions, its instruments measure the cosmic microwave background with exceptional precision, placing stringent constraints on early-Universe physics.
The lantern slides are transparent photographs or paintings on glass plates designed to be projected onto a screen using an early slide projector. They were sitting in three plastic tubs in a Fuertes office.
This system is truly extraordinary. We're seeing the radio equivalent of a laser halfway across the universe. Fundamentally, masers and lasers are focused beams of light in the same frequency. In the realm of astrophysics, these can arise from clouds of dust being excited into a higher energy state from the light emitted by other sources, like stars and black holes.
Chances to see 4 bright planets with your own eyes occur every few years on average, so it's not once in a lifetime. Even so, the planets are best observable just after sunset, so this is one of the most convenient opportunities for several years.
We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.
The universe is exploding. Or parts of it are. The night sky may seem calm, even serene, but that masks events of a catastrophic and nearly unimaginable scale. Across the galaxy and even the cosmos itself, immense outbursts of energy occur that could easily vaporize our planet. Happily, space is vast, and the terrible distance between these events and us diminishes what we see to a faint glowusually.
The first time that University of Oxford astronomer Lyla Jung saw the cosmic configuration on her monitor, she almost didn't believe it was real. But it wasand Jung and her colleagues went on to identify one of the largest rotating structures ever found in space: a chain of galaxies embedded in a spinning cosmic filament 400 million light-years from Earth. The finding, published in Monthly Notices of the Royal Astronomical Society, may give astronomers new insights into galaxies' formation, evolution and diversity, Jung says.
After years of traveling the globe in search of the darkest skies still possible in an increasingly bright world, I've learned something that surprises a lot of people: truly experiencing the night isn't just about where you go-it's about when you go. If I had to share just one astrotourism tip with travelers, it would be this: plan your trip around the new moon. It sounds almost too simple, but the difference it makes is dramatic. When the moon is absent from the night sky, darkness returns in a way that feels almost ancient. Stars multiply. Constellations become easier to trace. And in truly dark places, the Milky Way often reveals itself as a glowing, dusty band stretching from horizon to horizon.
There is a profound, quiet magic in standing alone under a truly dark sky, but the experience becomes something else entirely when shared with a community of fellow explorers. Star parties are the heartbeat of this experience: communal, high-energy gatherings where everyone from veteran astronomers to total beginners can share a wide-angle view of the cosmos. It's a chance to level up your astrophotography skills, learn the latest in deep-space science from experts,
Looking skyward fills us with wonder. Off-world, the Sun, planets, stars, and galaxies all await. Our Solar System encompasses our own cosmic backyard. Farther away, stars and star clusters abound within the Milky Way. Hundreds of billions of stars exist just within our home galaxy. Inside our Local Group, only Andromeda surpasses us in mass, size, and stars. More than 5 million light-years away, galaxies abound in groups and clusters.
Except for penguins and Antarctic scientists, few will be able to enjoy February's annular solar eclipse. That's because this eclipse will see the moon pass between the Earth and sun across the path of the southern continent, reaching a maximum at around 12:12pm UTC. People living in Eswatini, Lesotho, Madagascar, Mozambique, South Africa, Zimbabwe, and the southern parts of Botswana, Malawi, Namibia, Tanzania and Zambia, will only see a partial eclipse March 3.
Last week AES Andesa subsidiary of the AES Corporation, an American energy companyannounced it had scrapped its plans for a sprawling, city-size renewable energy project in Chile's Atacama Desert. The Atacama offers some of the world's darkest, clearest skieswhich is why it also hosts several of Earth's most important ground-based telescopes, including those of the European Southern Observatory's (ESO's) Paranal Observatory, which could've been within a mere five kilometers of the green-energy facility, according to earlier plans.
A bright star in a nearby galaxy has essentially vanished. Astronomers believe that it died and collapsed in on itself, transforming into the eerie cosmic phenomenon known as a black hole. "It used to be one of the brightest stars in the Andromeda galaxy," says Kishalay De, an astronomer with Columbia University and the Flatiron Institute. "Today, it is nowhere to be seen, even with the most sensitive telescopes."
Earlier this week, the Sun unleashed a powerful X-class solar flare, a major burst of electromagnetically charged particles that lit up the Earth's night sky as they entered our planet's atmosphere. The effect was stunning: a dazzling display of auroras reaching as far as southern California. Forecasters that it was one of the largest solar storms in decades, making for a particularly unique opportunity to watch the show unfold.
