My cell phone rang from the passenger seat of my car as I crossed the last intersection before a two-mile stretch of Hydraulic Road leading to Albemarle High School, my […]

In the nineteenth century, filibusters were rarer than visible comets. Now they are as common as sunsets—and as destructive as tsunamis, says The New Yorker’s Hendrik Hertzberg.

There has long been a desire to prove a connection between Earth’s geological activity and the gravitational resonance of the moon and the sun. Is there any truth to this claim?

Malcolm Hartley is an Australian astronomer who is best known for his discovery of 5 comets during the 1980s. He has been invited to NASA’s Jet Propulsion Laboratory in California […]

My mailbox is overflowing with questions from viewers who have watched “Sci Fi Science.” It would take too long to answer all of them, but let me answer a few […]

Yesterday, SpaceX became the very first commercial company in history to re-enter spacecraft from low-Earth orbit. Another first was on November 23rd when the Federal Aviation Administration (FAA) issued a […]

NASA is in a catch 22 situation.  Five years ago, Congress mandated by law that NASA should track 90% of all of the dangerous asteroids and comets that may threaten […]

I am proud to announce that the second season of “Sci Fi Science: Physics of the Impossible,” debuts next Wednesday, Sept. 1, at 9 pm, on the Science Channel (check […]

So let’s now speak about the future. You may have heard about the asteroid Apophis, which is about the size of the Rose Bowl Stadium. It’s said that the large […]

Nothing like a good Nature paper to get the media’s attention, especially when it was about the biggest air traffic disruption in almost a decade. Of course, the headlines I […]

Prior to the famous extinction of the dinosaurs, another mass extinction paved the way for their emergence, an emergence that happened much faster than previously thought, says The Economist.

Released just yesterday, Physics of the Future is my most ambitious book to date. Based on interviews with over three hundred of the world’s top scientists, who are already inventing the […]

Astronomer Chris Impey surveys the possible causes of earth’s extinction. Whether it come from an asteroid or the sun’s implosion, the rock we live on is by no means an eternal home.

Festive cheer is upon us, and some of it is even permeating this blog. But what does Christmas have to do with cartography? Well, there is Christmas Island – three […]

If the Earth is hollow, where does all that magma spewing out of all those volcanoes come from? Somebody must have a half-convincing answer to that question, presumably that handful […]

Two teams of researchers have confirmed that an asteroid circling the sun between the orbits of Mars and Jupiter has water ice and organic compounds.

I would like to thank everyone who has been so enthusiastic about being part of SCI-FI Science: Physics of the Impossible on the Science Channel. We have been floored by […]

IMAX Hubble 3D, hitting the theaters on March 19, features the most famous space telescope of all, the Hubble, launched in April 1990. Soaring above the earth’s atmosphere, it gives […]

New evidence suggests that remnants of Martian microbes were transported to Earth in a meteorite that crashed into Antarctica 13,000 years ago.

Hundreds of Jupiter-like planets and a handful of Earth-sized plants have been discovered by astronomers fuelling hope of finding alien life forms.

Will aliens look like the people next door? I hope not.

According to NASA, there is a green comet named Lulin approaching Earth. One astronomer calls it “a green beauty that could become visible to the naked eye any day now.” […]

Heidi Hammel’s team of scientists put the Hubble Space Telescope “back on the map” when they captured the dramatic collision of Comet Shoemaker-Levy 9 with Jupiter. Hubble performed “beautifully, flawlessly, […]
