Physicists Solve a 50-Year Mystery About a Critically Important Molecule

After relying on an educated guess for decades, scientists have finally confirmed the dipole moment of aluminum monochloride (AlCl), an elusive but important molecule known to sneak around the interiors of ancient galaxies. An electric dipole moment is a measure of polarity—a crucial determinant for many physical properties of any system, such as its boiling point or solubility. Given its importance, the new result, published last month in Physical Review A, presents exciting opportunities for

Astronomers Just Took the First-Ever Picture of the Bottom of the Sun

Astronomers have gotten an unprecedented view of the bottom of the Sun. On Wednesday, the European Space Agency shared images that show, in all its tumultuous glory, our star's secretive south pole. Captured by the Solar Orbiter spacecraft, the stunning achievement has paved the way towards solving some of the Sun's most abiding mysteries, and could even provide us the insight needed to predict some of the star's volatile behavior that can disrupt our modern infrastructure on Earth. "Today we

Solar Orbiter gets world-first views of the Sun's poles

Science & Exploration Solar Orbiter gets world-first views of the Sun’s poles 11/06/2025 31324 views 95 likes Thanks to its newly tilted orbit around the Sun, the European Space Agency-led Solar Orbiter spacecraft is the first to image the Sun’s poles from outside the ecliptic plane. Solar Orbiter’s unique viewing angle will change our understanding of the Sun’s magnetic field, the solar cycle and the workings of space weather. Solar Orbiter zooms into the Sun’s south pole Any image you have

See the Sun in a Way You've Never Seen It Before, From Above and Below

Every image you've ever seen of the sun is looking at its equator, because Earth's orbit sits there with a 7.25-degree tilt. That means humans have never had a good angle to view the sun's north and south poles until now. The ESA has released images of the sun's north and south poles, giving everyone their first glimpse at the top and bottom of our nearest star. The imagery was taken by the ESA's Solar Orbiter, which began its trek to view the sun's polar regions in 2020. To do this, the Orbite

Solar Orbiter Captures First Clear Views of Sun’s South Pole—and It’s a Hot Mess

For more than 60 years, various spacecraft and telescopes have journeyed through space to stare at the Sun, capturing haunting images of the giant ball of hot gas at the heart of our solar system. Our view of the star is limited, however, by Earth’s orbital plane, which allows us to observe the Sun’s equator head-on while its polar regions remain in a frustrating blind spot. Solar Orbiter is now the first to image the poles from outside the ecliptic plane, offering a rare look at its chaotic mag
