The Moon’s Dark Seas Are Scars From Ancient Strikes—Even Bigger Than We Thought

When you look up at a full or full-ish Moon you can’t help but notice the large dark spots that mark its Earth-facing side. These form the face of what many call the “Man in the Moon” (or the body of a Moon rabbit, to others) and are individually called mare (“MAR-ay”) which is the Latin word for sea. Early astronomers thought they were bodies of water, but in reality they are solidified dark lava flows from ancient lunar impact events that occurred several billion years ago.

One of the biggest lunar seas, Mare Imbrium (see above), had for a while been thought to have been created by the impact of an asteroid or meteorite somewhere around 50 miles across, based solely on computer models.

Now, research conducted by Brown University professor Dr. Peter Schultz—a specialist in lunar and planetary impacts—indicates that the object that formed Mare Imbrium was likely more massive and of much larger size than once thought…perhaps even as big as 190 miles wide.

Did NASA Purposely Cut Space Station Footage of a UFO?

Screen Shot 2016-07-13 at 5.19.07 PM

A truly “unidentified” object on ISS live feed on July 9, 2016…WHAT COULD IT BE?

Various news outlets today have run with a story about a supposed UFO spotted on live video streamed from the International Space Station, in which a bright object is visible “descending” into Earth’s atmosphere. The video* was shared on YouTube by a self-proclaimed UFO hunter—which basically means someone who stares at ISS feeds on their computers until their eyes melt and any speck of anything seen moving is instantly circled, copied into a slow-mo edited version, and overlaid with ominous music and/or bold text highlights claiming alien visitation and government cover-ups. (Views ensue.)

To help this particular spotting along is the fact that the feed cut out just as the object nears the edge of the atmosphere. Assured proof of a galactic-scale conspiracy by NASA and the NWO, right???

Please. Here’s my two-and-a-half cents:

Watch Juno’s Arrival at Majestic Jupiter, Moons and All

We are the stewards of over 400 years of scientific exploration of our Solar System, which it could be said began in earnest when Galileo Galilei first observed the motions of Jupiter’s moons in his homemade telescope in 1610. Over the centuries our knowledge—and our curiosity—about the seemingly endless variety of worlds in the Solar System has grown in leaps and bounds since Galileo’s first peeks at Jupiter, with increasingly more powerful telescopes both on Earth and in space and eventually even machines sent to join the planets in orbit around the Sun.

Last night NASA’s Juno spacecraft became humanity’s most recent emissary to the Solar System’s biggest planet, successfully performing the rocket burns needed to enter orbit around Jupiter—the first spacecraft to do so in 13 years. Amongst much excitement and deserved congratulations of the mission team, the video above was released showing Juno’s view as it approached the enormous planet the week before arrival after five years and 1.7 billion miles of travel. It’s dramatic and impressive and beautiful…just as it should be, considering the scope and achievement of the mission and the information that will soon be returned. Congratulations Juno!

“With Juno, we will investigate the unknowns of Jupiter’s massive radiation belts to delve deep into not only the planet’s interior, but into how Jupiter was born and how our entire solar system evolved.”
— NASA Administrator Charles Bolden

We Still Don’t Know What Exploded Over Tunguska in 1908

This is an article, now updated, that I originally posted in 2009 during my first year of blogging. Since then more research has been done on the famous 1908 Tunguska Event and we even had a remarkably similar type of thing occur in February 2013 over the Chelyabinsk area, not too far from Tunguska, but even today, the 108th anniversary of the event, scientists aren’t in agreement over what it was that violently exploded over the boggy forests of Siberia—asteroid or comet.

Flattened trees in Siberia from a 1908 atmospheric explosion

Long the subject of debate, with various theories ranging from meteorite impact to a comet to a flying saucer’s sudden engine meltdown, there’s actually strong evidence that the 1908 “Tunguska Event” was likely caused by the explosion of a comet in the upper atmosphere.

This idea has been suggested before, and is supported by Cornell University engineering professor Michael Kelly’s study of – strangely enough – the space shuttle’s exhaust plumes and their effect on high-atmosphere cloud formation.

To those not familiar with the Tunguska Event, something exploded or impacted in the remote area of Russia on June 30, 1908, flattening the forest in an 830-square-mile area, but leaving no visible crater or other obvious sign of what caused the event. Nearby residents reported the sound of a massive explosion, but that’s about it. Whatever it was, the devastation it caused was extensive and undeniable.

Icy Nix Indicates Pluto’s Moons Are Leftovers From a KBO Collision

Recent findings from the New Horizons team reveal that Pluto’s third-largest satellite Nix is covered in the purest water ice yet observed in the dwarf planet system, even purer in spectra than what was seen on its slightly larger sibling Hydra. This analysis further supports the hypothesis that Pluto’s moons were created in an impact event that formed the Pluto-Charon system, over 4 billion years ago.

Solar Photographer Spots Mercury On Its Trip Across the Sun

The May 9, 2016 transit of Mercury captured on camera by Alan Friedman.

The May 9, 2016 transit of Mercury captured on camera by Alan Friedman.

On May 9, 2016, over the course of seven and a half hours beginning at 7:12 a.m. EDT (11:12 UTC) Mercury passed across the disk of the Sun, appearing to observers on Earth as a small dark dot in front of the massive brilliance of our home star. While the event wasn’t visible to the naked eye (the Sun is just too bright and Mercury just too small) those with filtered telescopes and solar projection devices (like what I had set up) were able to see Mercury silhouetted against the Sun, and that most certainly included solar photography master Alan Friedman who captured the amazing image above from his home in Buffalo, NY.
