A Giant Space Laser on Earth Could Blast Messages at Alien Planets

And hey, it might work within “decades to centuries.”
Scientists want to equip Earth with some planetary porch lights.

What do the six-tailed Great Comet of 1744 and Comet McNaught of 2007 have in common?
Posted by Michael Lance in category: space
Aside from being comets, they both offer valuable insight about how solar wind affects the dust tail—the long stream of dust following in the comet’s path. Scientists used a temporal map, which layers information from multiple images, to discover that variations of solar wind push the dust around like a ruffled feather—suggesting that the dust is electronically charged. This discovery sheds light on the processes that formed dust into asteroids, moons, and planets in the early days of our solar system.

Does antimatter fall upwards? New CERN gravity experiments aim to get to the bottom of the matter
Posted by Genevieve Klien in categories: physics, space
Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate – as famously demonstrated by an Apollo 15 astronaut on the Moon. Now, CERN scientists are preparing to put a spooky new spin on that experiment, by dropping antimatter in a vacuum chamber to see if gravity affects it the same way it does matter – or if antimatter falls upwards instead.

Feeling high with Diwata-2 in the sky
Posted by Michael Lance in categories: business, space
What was it like to see, up close, the H-IIA rocket (that carried Diwata-2) leave the grounds of Japan’s Tanegashima Space Center last October 29? Here’s a firsthand account from BusinessMirror.
WHILE waiting for the launching of Diwata-2 at the view deck in Tanegashima Space Center in Kagoshima, Japan, with our cameras trained at the launch site, Dr. Joel Marciano, the head of Philippine Scientific Earth Observation Microsatellite Program (PHL-Microsat) whispered: “Don’t just look at the rising rocket [named H-IIA F40 that carries Diwata-2] through your camera. Look at the real event so you can feel it.”
I didn’t know and did not have the time to ask what he meant by “feel it.”
The International Space Station is your orbiting laboratory, and the science being conducted there will help us push farther into deep space, while providing benefits back on Earth. Microgravity unlocks new worlds of discovery. Dive into what we’re learning: 🔬🚀.

We have an official green light for “Lucy,” launching in 2021
Posted by Michael Lance in category: space
Lucy is a mission to primitive asteroids orbiting Jupiter, where we’ll learn about planetary origins and the formation of the solar system. Lucy will complete a 12-year journey to seven different asteroids, more destinations in independent orbits than any space mission in history.

What the general theory of relativity doesn’t explain
Posted by Genevieve Klien in categories: physics, space
100 years ago Einstein first described his general theory of relativity. This theory had a profound effect on physics and our understanding of the universe.
