Beyond SETI – Time to Start Calling The Cosmos?

Most every one has heard of SETI — the Search for Extraterrestrial Intelligence — and most also know that, so far, the scientists that operate the powerful telescopes and computers that analyze potential signals from civilizations beyond Earth have come up empty-handed — with the possible exception of the so-called ‘Wow! signal’ (detected only once, […]

Recurring Meteor Shower On Mercury? NASA’s MESSENGER Suggests So

Does the planet Mercury have regular meteor showers like the Earth does? Apparently so, based on recent findings/data from NASA’s MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft. The “discovery” is coming to us via clues found in the very thin halo of gases that make up the planet’s exosphere — clues found by […]

Pulsar Tug-Of-War Warps Space-Time Itself, Research Finds

An incredible tug-of-war between the two stars in the binary pulsar system J1906 actually warps space-time itself owing to the powerful effects of each on the other. Owing to its spin, the pulsar emits a sort-of lighthouse-like beam of radio-waves roughly every 144 milliseconds. New research from the University of British Columbia has now resulted […]

Best Elon Musk Interview Yet?

Here’s a really interesting interview with the head of Tesla Motors, SolarCity, and SpaceX — Elon Musk. This is perhaps the most interesting interview I’ve seen with him, as it runs through life stories from age 6 to today. For some reason, it took me ages to get to this, and it is actually from 2013, but […]

We Expect To Land On A Comet Today… [UPDATE: Done.]

It’s only taken ten years and four billion miles. The European Space Agency’s Rosetta spacecraft, a two-part probe with orbiter and lander, arrived at comet 67P/Churyumov-Gerasimenko on August 6 after the long trip. [UPDATE 10:50 CST: Philae’s on the ground!] Despite a faulty thruster, Rosetta successfully launched Philae, the 220-pound lander, from orbit several hours ago. […]

Blood Moon Wednesday AM Preps Earth for Halloween

This year, nature brings us a special pre-Halloween treat: a blood moon. In the US and Canada, lift your eyes skyward in the early hours tomorrow morning for the second total lunar eclipse of 2014. The Moon veiled slowly red and back the first time this year in April. Just over 5% larger than that phenomenon, Wednesday […]

Cassini Observes Strange Feature In Hydrocarbon Seas On Saturn’s Moon Titan

A rather strange-looking “feature” was recently observed forming, and changing, in the hydrocarbon seas of Saturn’s moon Titan by NASA’s Cassini spacecraft. The interesting feature covers an area of over 100 square miles (260 square kilometers) in Ligeia Mare — one of the biggest seas on Titan. Cassini has now observed the feature twice, with […]

Last 2014 Supermoon Tonight!

Time to look up again tonight (Tuesday, September 9) for the last of five Supermoons this year! This one won’t be as spectacular as the August 10 recordbreaker, but it offers a terrific spectacle. The moon will not be as close to Earth as this until the full moon of September 28, 2015. The September […]

Perseids Meteor Shower Peaks Tonight, On August 12 2014

The highly prolific Perseids meteor shower will be reaching its for peak for the year tonight, on August 12 2014 (early morning hours of August 13 2014). Peak activity is expected to be somewhere around 100 meteors an hour when seen from a dark rural location — so when you factor in the very bright […]

“Origami Robots” Self-Construct And Start Working

If you haven’t seen the origami robot yet, you’re in for a fantastic surprise! Evoking the potential of an ancient and wonderful Japanese art, these crawling robots can self-assemble from flat-pack designs and autonomously perform. Inspired by self-assembly in nature—such as the way complex proteins with sophisticated functions derive from folding linear sequences of amino […]

NASA-ESA’s Hubble Finds Zombie Star

When we think of a supernova, we usually think of a massive explosion that wipes out the entire white dwarf star (dying stellar body). However, thanks to a collaboration of research scientists from leading American astronomers and astrophysicists and the Department of Physics and Astronomy, Aarhus University, we now know that isn’t always the case. In […]

Largest Supermoon Of The Year Comes On Sunday, August 10

The closest full moon of 2014 occurs this week, on Sunday, August 10, at 2:11 p.m. EDT. It’s the fourth and biggest of 2014’s five rogue Supermoon events. We’ll be able to see the Moon reach its perigree, when it draws closer to the Earth than at any other time during 2014. As we noted […]

Double Feature: Delta Aquarids And Some Perseids Overhead This Week

Two meteor showers come out of the constellation Aquarius (the Water Bearer), nearest the dim star Delta Aquarii, this time of year: the southern and northern Delta Aquarids. The peak for the southern Delta Aquarids, which are starting Monday and Tuesday, is very gradual, so anytime this week should provide good viewing. The Southern Hemisphere […]

Happy 45th Anniversary: Humans Land On The Moon

PlanetSave would be remiss if we didn’t say something today to recognize that 45 years ago humans first set foot on another celestial body. Launched on an expendable multistage liquid-fueled Saturn V rocket on July 16th, 1969, Apollo 11 crew left Earth for the first human mission to land on the Moon. Commander Neil Armstrong, Command Module Pilot […]
