Lessons from Simulating Intergalactic “Pancakes”: Studying the Nature of Matter Between Galaxies

Lessons from Simulating Intergalactic “Pancakes”: Studying the Nature of Matter Between Galaxies

“We are stardust,” sang Joni Mitchell at Woodstock. Yes, with the exception of dark matter, the atoms that make up the vastness of space and all the galaxies within it are essentially the same as the atoms that make up

Curious Methods: Bright Life: Biofluorescence Provides a New Way to Search for Extraterrestrial Organisms

Does alien life exist? Previous efforts to search for extraterrestrial life have only yielded inconclusive answers. Recently, however, two astronomers at Cornell University pioneered a new method of detecting extraterrestrial life. Jack O’Malley-James, from the Cornell Center for Astrophysics and

Slicing Cells with Light: New Microscopy Techniques Shed Light on Life’s Intricacy

Life exists at various scales, some visible and others too small to see—microscopic. Humans are, on average, a meter and a half. Zoom into our bodies and you’ll see organs measurable with a ruler. Keep going and you’ll encounter cells,

What is a Black Hole?

What is a Black Hole?

The term “black hole” was coined in the 1960s by physicist Robert Dicke, aptly deriving from the Black Hole of Calcutta, an inescapable prison. But various fields of science assign different properties to these stellar objects—an issue professor Erik Curiel

Some Dark Matters: Newly discovered galaxies lack dark matter

For astronomy researchers, the invisible nature of dark mat­ter is one of the most perplexing features of our universe. Dark matter is a theoretical form of matter that does not interact with light, and therefore cannot be directly observed by

To Mourn a Star: A hot and fast ultra-stripped supernova that likely formed a compact neutron star binary

Imagine a material so dense that a teaspoon of it weighs as much as 900 Pyramids of Giza. Some objects in the universe really are this dense: neutron stars. Despite their confusing name, they are not stars; instead, they are
