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 […]

Heavens Above has just the features you’re looking for. It’s dedicated to helping people observe and track, with only the naked eye, satellites orbiting Earth. Chris Peat, a physicist and space-industry […]

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 […]

OCO-2 Set To Outfox Climate Change Denial

OCO-2 is only a little thing, about 6 ft long, 3 ft in diameter, and less than half a ton in weight (NASA/JPL-Caltech, artist’s conception).  It will be harder to deny the existence of climate change now that NASA has successfully launched Orbiting Carbon Observatory-2.  A United Launch Alliance Delta II rocket from Vandenberg Air […]

Seeking Proof Of Intelligent Life In The Universe? (cartoon and essay)

Extraterrestrial life—life that does not originate from Earth—has been a subject of speculation since Copernicus theorized that Earth is not unique in the Universe. Intelligent life in the cosmos is actually a great explanation for the Pyramids, Stonehenge, and a lot of other peculiar structures in the world. (Crop circles, however, remain a mystery to […]

NASA’s IRIS Captures A Huge Sun Sneeze (CME)

The National Aeronautics and Space Administration scored an impressive first a few weeks ago by capturing an enormous solar coronal mass ejection with its new Interface Region Imaging Spectrograph. A CME is a massive burst of solar wind and magnetic fields that rises above the solar corona and may be released into interplanetary space. NASA […]

Fast Forward To A Gobbled-Up Milky Way

You may have heard that the days of our home galaxy, the Milky Way, are numbered. The Milky Way is one of the dominant galaxies of a cluster known as the Local Group. The other major player in the group is the Andromeda nebula (M31). And according to recent measurements by the Hubble Space Telescope, […]

It’s the best night all year for viewing our feisty little sunmost neighbor from Earth’s northern hemisphere. On this date, Mercury will reach its elongation—the farthest point it travels to the east […]

Meteor Shower Tonight — Camelopardalids Peak On May 23, 2014

A new, and possibly huge, meteor shower — the Camelopardalids — will be reaching its peak tonight (May 23, 2014) sometime right around 2-4am (EDT), for those of us in the continental US. To be clear, by “the night of”, I mean the very early morning hours of May 24, 2014. Current predictions are that […]

A new, and possibly spectacular, meteor shower will be gracing the skies on the night of May 23, 2014 (early morning of May 24, 2014). Predictions are that the shower could reach a peak rate of anywhere between 100-1000 meteors an hour — the most sober assessments seem to be pointing towards 200 an hour […]

Total Solar Eclipse Tonight, But Most Of Us Will Miss It

Tonight’s the first annular solar eclipse of 2014 (April 28-29), but almost nobody will be able to see it. The ring of fire will be visible only from the uninhabited region of Wilkes Land in Antarctica, the southern edge of Indonesia, and the South Indian Ocean. Australians will experience a partial solar eclipse, as may […]

Water Likely On New Terra-Like Exoplanet Kepler-186f

Artist’s conception of Kepler-186f in its solar system (NASA Ames/SETI Institute/JPL-Caltech) It’s a bit less possible now that we’re alone in the universe. The $600-million Kepler Space Telescope, launched five years ago to identify planets, has spotted more than 3,800 and confirmed 966 of them. The last one, fifth planet of a star in the […]

A Special Solar Drone For Social Media

Drones are no longer known as mere weapons of war. At least, that’s how Google, Facebook, and other online giants like Amazon appear to be thinking. Google has just acquired Titan Aerospace, a promising solar-powered drone maker, as part of its plans to globalize wireless internet. Titan’s website provides news that the company is working […]

Eclipse: Full Shadow Covers The Moon Tonight!

It’s not just the annual income tax deadline that expires tomorrow. The Moon will also be going out—though like taxes, it will reappear, and 364 days sooner. In the wee hours of tomorrow morning, stargazers in the Western Hemisphere will start losing sight of the moon. For 78 minutes, the southern half of Earth’s umbral […]

Tonight’s The Night For Catching Mars

Mars in opposition (NASA graphic). The Fourth Rock comes closer to us on Tuesday, April 8, 2014, than it has for the past seven years. Not only is the Red Planet in opposition—-directly in line with both earth and the sun—but the opposition is “favorable.” Mars has a slightly elliptical orbit and it will be […]

Asteroid Disintegration Spotted By NASA's Hubble — Never-Before-Seen Phenomenon

The incredibly rare sight of an asteroid’s disintegration was recently captured in a series of images by NASA’s Hubble Space Telescope. The images show (in great clarity) the never-before-seen process of a fully intact asteroid coming apart — into ten pieces in this instance. While fragile comet nuclei have been observed disintegrating during close approaches […]

Does The Future Of Humanity Lie In Space?

World-renowned astrophysicist Stephen Hawking, and Buzz Aldrin, the second man to walk on the moon, are united by a common belief. They are members of an influential group of scientists and visionaries who believe that the long-term future of the human race lies in space, and that we need to grow beyond the confines of […]

Supernova SN 2014J Observations Challenge Old Assumptions

The recent discovery and subsequent observations of the supernova SN 2014J have led researchers to realize that the primary ‘yardstick’ used by astronomers to measure cosmic distances may not be such a constant after all. Six weeks ago (on January 21), a super-bright supernova was discovered in the nearby galaxy of M82, by researchers in […]
