Spain will hold the unique distinction of being the only country worldwide where the final phase of a total eclipse can be observed. Occurring in the summer months, these eclipses also benefit from a higher likelihood of clear skies, ensuring optimal viewing conditions.

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.

Despite decades of searching, SETI scientists have found no evidence of ET signals from space. The lack of success could be due to the staggering amount of data that must be collected and analyzed.

A meteoroid-a small body moving through space-is called a meteor when it encounters a planet's atmosphere and subsequently produces a bright streak of light. This occurs because the meteoroid is traveling many times faster than the speed of sound.

We are firmly in the era of the satellite constellation—groups of dozens of similar satellites—and are currently entering the era of the mega constellation, wherein groups of thousands of satellites swarm the skies. The clusters of satellites started small, but, like a viral outbreak, they grew almost without us noticing—and now we're dealing with a pandemic.

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.

A rare planetary lineup from late February will continue into early March, with six planets-Mercury, Venus, Saturn, Jupiter, Uranus, and Neptune-appearing to trace the same path across the sky, known as the ecliptic. Because Mercury, Saturn, and Neptune set soon after sunset, you'll need to look shortly after twilight to see all six at once.

One of the most exciting aspects is the rich chemistry we detect. We see dozens of different molecules, including some complex organic molecules that contain carbon, the same element that forms the basis of life on Earth. From ACES, we are learning more about how the ingredients for planets, and potentially life itself, can arise in the universe.

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.

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.

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.

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,

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.

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.

The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we sometimes picture, the sun's surface is made up of roiling plasma thrown about by twisting magnetic fields. When these fields snap, they can throw out huge bursts of energy and charged particles into spacea solar flare.

Astronomers may have finally solved one of the weirdest mysteries of our night sky: why Betelgeuse, a massive star in the constellation Orion, seems to fade and brighten as if it were operated by a heavenly dimmer switch. Using the Hubble Space Telescope and ground-based observatories, scientists observed Betelgeuse for almost eight years and found that patterns in the star's light suggested the wake of another, unseen star was passing through its atmosphere.
