On January 20/21, half of Earth will experience a total lunar eclipse. For the first time in 19 years, this includes all of North and South America. When the Sun, Earth, […]
We can describe what we see happening, but we don’t understand why. Despite our vast cosmic knowledge, enormous unknowns remain. The quantum fluctuations inherent to space, stretched across the Universe […]
The raw ingredients just weren’t there. Thankfully, their predecessors were. Here on Earth, our planet practically overflows with life. After more than 4 billion years, life has spread to practically […]
Is it groupthink? Or is there a deeper reason? In the early half of the 20th century, even after the discovery of the expanding Universe, physicists considered a wide variety of […]
Now is a good time to brush up on who's on the ballot.
From newborn planets to entire galaxies, we’re seeing the Universe as never before. The idea of a modern telescope is simple: collect light from a distant object, at high resolution, and […]
What happened 4.56 billion years ago is the most important part of the cosmic story ever to happen to us. If you were to look at our Universe at the time […]
If all you see is low-energy light in a myriad of directions, you can’t be sure. But this light comes from the Big Bang. There are a lot of things that […]
The ‘big event’ was billed as a first in 150 years. But is what we’re seeing really that rare? This January 31st, something quite rare and special will happen. At 1:30 […]

As wonderful as the evidence that supports or invalidates a theory is, it can never truly kill the ones that don’t work out. When it comes to science, we like to […]
Multiple teams of scientists can’t agree on how fast the Universe expands. Dark matter may unlock why. There’s an enormous controversy in astrophysics today over how quickly the Universe is expanding. […]
I’m not saying it wasn’t aliens… but… it wasn’t aliens. “Just the fact that you so desperately attempt to dismantle our theory proves that we are on the right track. Otherwise […]
The Los Angeles Hope Festival is the celebration and examination of hope and optimism, two paradigmatic mental attitudes that play a vital and influential role in our daily lives.
How sure are we that what we’re looking at is cosmic, rather than galactic? “Every philosophy also conceals a philosophy; every opinion is also a hideout, every word also a […]
The Bubble Nebula, including the bright star that powers it, the “shell” of material blown away by the stellar winds and the surrounding molecular cloud. Image credit: NASA, ESA, and […]
Robin Williams was trapped inside his own rapidly-deteriorating brain, which was being overtaken by what his wife refers to as a "terrorist" — Lewy Body Disease.
Want the speed of light, the fine-structure constant or others to change? There’s a new obstacle to overcome. “The mystery about α is actually a double mystery. The first mystery — the […]
And if it is, what does that mean for dark energy, and our Universe’s fate? “Until the 1990s, there were few reliable observations about movement at the scale of the […]
