This Cool Video Shows You All ~600,000 Asteroids Discovered In Our Solar System Since 1980

Scott Manley is a self-described “astronomer, hacker, gamer, DJ” from Scotland. He is also an avid YouTuber. A few years back, Manley created an awesome visualization showing the discovery of new asteroids in our solar system since the year 1980. Originally posted back in 2010, Manley updated the video this past June to include all of the approximately 600,000 asteroids that have been found over the past 34 years. Check it out! Even compared to Mercury (the smallest planet in our solar system),

Earth’s Magnetic Field Is Weakening 10x Faster Than Previously Thought

We often take it for granted that the North Pole is at the top of the globe and the South Pole is at the bottom. But in reality, these poles have flip-flopped a number of times in Earth’s history, the most recent being about 780,000 years ago. Each flip is preceded by a gradual weakening of the magnetic field. Since the early 2000s, scientists have been predicting that the next polar flip would happen in the next 5,000 years or so, based

A Few Reasons Why Tomorrow Might Be A Bit of a Strange Day…

Tomorrow will not be your ordinary Friday. For starters, tomorrow is the 13th, making tomorrow a Friday the 13th. There will also be a full moon in the sky when the clock strikes 12:01 a.m. tomorrow morning. The last time that happened? October 13, 2000. The next time it will happen? August 13, 2049. I’m not one for superstitions, but there is one thing I haven’t mentioned yet. Our sun has been shooting off powerful solar flares the last few days, including this one captured

Watch A Four-Year Timelapse of A Mysterious Cosmic Explosion Captured By the Hubble Telescope (Video)

Back in January of 2002, astronomers witnessed a huge explosion from the star V838 Monocerotis, a red variable star about 20,000 light years away from our Sun. At first, they thought it was a typical supernova (the explosion of a dying star), but after watching the explosion dim then brighten twice over a period of only a few months (supernovas will usually only dim after the initial bright explosion), astronomers really weren’t sure what they were dealing with. Check out a time-lapse of the

What It Looks Like When Two Neutron Stars Rip Each Other Apart to Form a Black Hole (Video)

black hole neutron star

A neutron star is what’s left behind when a massive star (typically 8-30 times the size of our Sun) explodes into a supernova. These supergiant stars get so large that they are no longer able to remain stable under their own intense gravity and collapse in on themselves. The gravity is so massive that it exceeds the strength of the atomic forces that hold the actual atomic particles within the star together. As a result, the atoms their protons and electrons, leaving behind

Blowing the Top Off a Mountain to Build a Telescope So Big It Can See Signs of Life On Other Planets

In a few short weeks, engineers in the Chilean Coastal Ranges of the Andes Mountains in South America will be blowing off the top of Cerro Armazones.  Standing at 10,000 feet, it’s one of the tallest peaks in the region. Here’s Gird Hudepohl, the head engineer for the project: “We will take about 80ft off the top of the mountain to create a plateau – and when we have done that, we will build the world’s biggest telescope there.” The Coastal Ranges region is

So There’s This Kid Making Solar “Death Rays” And They’re Pretty Sweet (Video)

Eric Jacqmain is just a creative guy who wanted a death ray. So, he decided to cover a satellite dish with 5,800 tiny mirrors. This is from his video description: “When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 times normal daylight. This intensity of light is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant.” The end

If You Missed The Blood Moon You Can Watch The Whole Thing Here In Just 9 Seconds (Gif)

You may have heard people talking about the “blood moon” that happened last night. If you missed it, not to worry! Here’s the entire event (which took just under two and a half hours) in just 9 seconds: To learn more about what caused the blood moon checkout our post about the event from yesterday. Edit: Just found another cool gif of the event from another perspective-Enjoy!  

What Is A Blood Moon and Why Is It Happening Tonight During the Total Lunar Eclipse??

At exactly 8:58 p.m. CST (central time) tonight, the moon will move into Earth’s shadow. The total lunar eclipse, where the moon is completely shaded by the Earth, will start a little more than an hour later at 10:07 p.m. CST, and will last until approximately 11:25 p.m. CST. You may have heard the term “blood moon” before. Whenever the moon passes into Earth’s shadow, it takes on a reddish color- it can be anywhere from a bright copper to

The Solar Flare So Intense That Telegraphs Spontaneously Caught Fire

Back in 1859, Richard Carrington, one of England’s leading astronomers at the time, witnessed one of the most intense solar flares to hit Earth in recent history. Here’s the story from NASA Science: At 11:18 AM on the cloudless morning of Thursday, September 1, 1859, 33-year-old Richard Carrington—widely acknowledged to be one of England’s foremost solar astronomers—was in his well-appointed private observatory. Just as usual on every sunny day, his telescope was projecting an 11-inch-wide image of the sun on
