Starts With A Bang What was it like when the cosmic dark ages ended? For 550 million years, neutral atoms blocked the light made in stars from traveling freely through the Universe. Here’s how it then changed.
Starts With A Bang The Milky Way’s next supernova could reveal dark matter The last naked-eye Milky Way supernova happened way back in 1604. The next one could be the key to solving the dark matter mystery.
Starts With A Bang Ask Ethan: How did we prove the Big Bang took place? Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
Starts With A Bang IceCube finds neutrinos from 47 million light-years away IceCube just found an active galaxy in the nearby Universe, 47 million light-years away, through its neutrino emissions: a cosmic first.
Starts With A Bang How many types of precipitation can a planet have? All across the Universe, planets come in a wide variety of sizes, masses, compositions, and temperatures. And most have rain and snow.
Hard Science Earendel: Hubble smashes record for farthest star ever seen The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
Starts With A Bang Ask Ethan: How is energy conserved when neutrinos oscillate? If there are three neutrino species, all with different masses, then how is energy conserved when they oscillate from one flavor to another?
Starts With A Bang Black hole science enters its golden age The idea of black holes has been around for over 200 years. Today, we’re seeing them in previously unimaginable ways.
Hard Science Dark matter: New detector will look for “ultra-light” particles Scientists are searching for dark matter particles that are trillions or even quadrillion times lighter than the more traditional searches.
The Past The 16th-century codebreaker who wrote secret messages on boiled eggs Giambattista della Porta’s contributions to codebreaking changed the course of communication.
Starts With A Bang Voyager 1 has left the Solar System. Will we ever overtake it? In all of human history, only 5 spacecraft have had the right trajectory to exit the Solar System. Will they ever catch Voyager 1?
Starts With A Bang Ask Ethan: Why is there something instead of nothing? Perhaps the most remarkable fact about the Universe is simply that it, and everything in it, exists. But what’s the reason why?
Starts With A Bang Have we found the Milky Way’s twin? Our galactic home in the cosmos — the Milky Way — is only one of many trillions of galaxies within in the observable Universe. Do we have a twin?
Starts With A Bang New Earth-threatening asteroid highlights humanity’s unpreparedness The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we’re woefully unprepared.
Hard Science Searching for Planet 9 Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.
Starts With A Bang What was it like when life first sprang forth on Earth? Although early Earth was a molten hellscape, once it cooled, life arose almost immediately. That original chain of life remains unbroken.
Business How leaders can overcome the fear of reinvention The challenges of setting out in a new direction can be overwhelming — but we can learn to navigate the inflection moments.
The Past Did ancient Greek philosophers believe in aliens? Speculation about the existence of aliens goes all the way back at least to the Greek philosophers. Their arguments will sound familiar.
High Culture 5 brilliant books that pioneered new subgenres of literature From “The Castle of Otranto” to “The Lord of the Rings” trilogy, these books changed the literary landscape.
Starts With A Bang What is astrophysics? If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go.
The Past Why the “father of the hydrogen bomb” hated Carl Sagan Teller and Sagan debated fiercely over nuclear proliferation. But was the conflict as personal as it was intellectual for Teller?
Starts With A Bang Inside JWST’s first view of the Local Group’s edge By studying the dwarf galaxy Wolf-Lundmark-Melotte ~3 million light-years away, JWST reveals the Universe’s star-forming history firsthand.
13.8 The Big Bang’s mysteries and unsolvable “first cause” problem The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.
Starts With A Bang Ask Ethan: How can you reason with a young-Earth creationist? Science is for everyone, even those possessing strongly held beliefs that seem to conflict with the best available evidence.
Starts With A Bang New JWST view showcases our cosmic isolation With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.
The Present A fusion rocket designed to travel 500,000 mph is under construction It could cut the time needed to reach Mars in half.
13.8 Why seeing the Milky Way’s supermassive black hole is such a big deal Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.
