Chester County, like much of Pennsylvania, will experience 90% totality during the solar eclipse on April 8.

The team will send weather balloons tens of thousands of meters into the atmosphere for experiments on gravity waves and the building blocks of the universe.

It will be another 21 years before the U.S. sees another total solar eclipse on this scale.

The moon's shadow will slice a diagonal line from the southwest to the northeast across North America, briefly plunging communities along the track into darkness.

When the April 8 solar eclipse draws eyes upward, having proper solar filters and solar eclipse glasses is essential to avoid potentially permanent eye damage, doctors say.

We look into the history of eclipses and what scientists are hoping to learn.

The new funding will help researchers evaluate the impact of offshore wind activities on whales, birds and the marine ecosystem.

Aravind Krishnan is developing technology that can test for bacterial toxins using a plant-based alternative to horseshoe crabs.

A new study published in Nature measures whether land across 32 U.S. coastline cities is sinking or rising, and combines it with sea-level projections.

Some scientists object to the whole idea of trying to revive extinct animals.

The project is part of an initiative from NASA and the National Science Foundation to collect data and give students a chance to learn about scientific ballooning.

How did a brilliant teenage physicist working on the Manhattan Project get away with spying for the Soviets? And why did he do it?

When apes diverged from monkeys, our branch of the tree of life shed its tail. From Darwin’s time, scientists have wondered why — and how — this happened.
