How can galaxies merge if the everything in the universe is moving apart?

How can galaxies merge if the everything in the universe is moving apart?

How is it that galaxies merge and collide but the universe is expanding and everything is moving away from everything else? Justin HammersleySterling Heights, Michigan Whether or not galaxies merge depends on how strong the gravitational attraction is between the galaxies and whether the universe’s expansion is more powerful than gravity. Gravity affects everything in Continue reading "How can galaxies merge if the everything in the universe is moving apart?"

2026 Full Moon calendar: When to see the Full Moon and phases

2026 Full Moon calendar: When to see the Full Moon and phases

The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moon’s orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back to Continue reading "2026 Full Moon calendar: When to see the Full Moon and phases" The post 2026 Full Moon calendar: When to see the Full Moon and phases appeared first on Astronomy Magazine .

This Week in Astronomy with Dave Eicher: Venus meets Saturn

In this episode, Astronomy magazine Editor Emeritus Dave Eicher invites you to head out on the evening of March 8 to see a close grouping of two planets. This time, brilliant Venus — the third-brightest object in the sky (next to the Sun and the Moon) will be passing by Saturn. Find Venus before twilight ends and look for Continue reading "This Week in Astronomy with Dave Eicher: Venus meets Saturn" The post This Week in Astronomy with Dave Eicher: Venus meets Saturn appeared first on Astronomy Magazine .

March 2, 2004: Rosetta launches

On March 2, 2004, the Rosetta-Philae spacecraft launched from French Guiana, with the goal of rendezvousing with a comet to learn more about the early solar system. The European Space Agency mission would need 10 years, three gravity assist flybys of Earth, and one gravity assist from Mars to get the spacecraft to its target. Continue reading "March 2, 2004: Rosetta launches" The post March 2, 2004: Rosetta launches appeared first on Astronomy Magazine .

Young cancer survivors face faster aging and possible early dementia

Young cancer survivors face faster aging and possible early dementia

Surviving cancer at a young age may come with an unexpected cost: faster aging at both the cellular and brain levels. Researchers found that survivors often show signs of being biologically older than their actual age, with chemotherapy accelerating the process most dramatically. This accelerated aging is linked to struggles with memory and focus, which can ripple into education and career outcomes. Encouragingly, scientists believe healthy habits like exercise may help turn back the clock.

A bold new plan could finally cure type 1 diabetes

A bold new plan could finally cure type 1 diabetes

Researchers are developing a two-part therapy for type 1 diabetes: lab-made insulin-producing cells paired with custom-engineered immune cells that protect them. The goal is to stop the immune system from destroying transplanted cells — without using immunosuppressive drugs. Backed by $1 million in funding, the team hopes to create a ready-to-use treatment that could work even for people who have had diabetes for years. The approach could transform how the disease is treated.

Ancient mystery on K’gari: World’s largest sand island lakes dried up during rainy era

Ancient mystery on K’gari: World’s largest sand island lakes dried up during rainy era

K’gari’s iconic lakes have existed for tens of thousands of years—but they haven’t always been full. New research shows that about 7,500 years ago, during a time of high rainfall, several of the island’s deepest lakes mysteriously vanished. Scientists believe changing wind patterns may have redirected rain away from the island. As the climate shifts again, the lakes’ long-term survival is no longer guaranteed.
