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:
This week NASA’s Jet Propulsion Laboratory announced news of an object traveling around the Sun in an orbit that keeps it relatively close to our own planet. The object, a near-Earth asteroid (NEO) less than 300 feet (100 m) across, is designated 2016 HO3 and has in some reports been called a “new” or “mini” moon of Earth…but that’s not entirely true. More accurately 2016 HO3 is what’s known as a quasi-satellite, and is in a temporary (albeit long-lived by human standards) orbit that takes it on a “leapfrog” path around Earth, never getting closer than 38 times the distance to the Moon—about 9.1 million miles.
I love models that demonstrate the incredible size and space of the Solar System, very much so because many illustrations and diagrams fail to portray it accurately (and for very good reason…it’s enormous.) The most recent is shown here, enthusiastically created and narrated by former NASA engineer Mark Rober. This particular demonstration is unique in that it’s the only one (that I’ve seen so far) that includes the newest possible-planet in the Solar System, “Planet Nine,” a Neptune-mass world that may orbit the Sun up to four times farther away than Pluto. Check it out above, and you can find some other cool scale models of the Solar System I’ve encountered previously below.
(And remember kids, space is really, really, really BIG.)
Captured by the EU’s Copernicus Sentinel-3A satellite on Feb. 29, 2016, this beautiful composition of blacks, purples, and blues shows the twilight transition across the Norwegian archipelago of Svalbard, located north of the Arctic Circle between Norway and the North Pole. The snow-covered and fjord-cut large island of Spitsbergen can be seen at the right edge, while sea ice and clouds follow their own swirling currents on and above the Greenland sea.
This is the first image acquired by the spacecraft, which was launched aboard a converted-ICBM Rockot vehicle on Feb. 16 from Russia’s Plesetsk Cosmodrome. The first of two planned Sentinel-3 satellites, 3A is currently in a high-inclination orbit at an altitude of 505 miles (814 km).
If you’re in love with space exploration then you’ll fall for this: a picture of Earth (and five other planets) taken from the Voyager 1 spacecraft after it passed the orbit of Pluto in 1990, 26 years ago today. That image of our planet from almost 4 billion miles away inspired Carl Sagan to write his famous “Pale Blue Dot” passage, and reminds us that we are all just floating on “a mote of dust suspended in a sunbeam.”
This is from a post I originally published in 2010. I’ll keep trotting it out until it’s not cool anymore. (Which
I don’t think will ever will NEVER happen.)
On February 14, 1990, after nearly 13 years of traveling the solar system, the Voyager 1 spacecraft passed the orbit of Pluto and turned its camera around to take a series of photos of the planets. The image above shows those photos, isolated from the original series and are left to right, top to bottom: Venus, Earth, Jupiter, Saturn, Uranus, and Neptune.
From that distance, over 4 billion miles from the Sun, the planets each appear as little more than a bright dot against the vastness of interplanetary space.
“That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. … There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world.”
