How fast are you moving right now? Maybe you’re reading this while sitting at home, where it seems as though you’re not moving at all. Stand still or sit down, and it feels like you are stationary, yet regardless of what you do, you are constantly in motion. That is because the Earth itself is rotating at a speed of around 1,000 miles per hour. In addition to its rotation, the Earth is also moving around the Sun at a speed of 67,000 miles per hour. Regardless of how stationary we feel, we move tens of thousands of miles every day. That may seem fast, yet the Earth is barely even moving compared to some things in the universe.

The Fastest Thing In The Universe

The universe itself has a cosmic speed limit. That is to say, there is a limit as to how fast objects within space can travel. That speed limit is approximately 186,000 miles per second, and there is only one thing in the cosmos that travels at that speed: light. Light is the fastest known thing in the universe, and thus the cosmic speed limit is called the speed of light. Regardless of how hard you try, you can never exceed the speed of light. Like gravity, the cosmic speed limit is a fixed law of nature that cannot be broken. Whether it’s coming from a star or your cellphone flashlight, every light beam will travel at 186,000 miles per second.

The Fastest Known Planet

Planet Kepler-78b

Over the last 30 years, scientists have uncovered thousands of planets that orbit stars outside our solar system. Many of these worlds are vastly different from those that orbit our Sun. Regardless of what type of planets orbit a star, one thing they all have in common is how their orbital velocity is related to the distance between them and their star. Planets that orbit close to their star will complete an orbit faster than planets that orbit further away. Mercury is the fastest planet in our solar system, completing one rotation every 88 days. That may seem fast, yet it is nothing compared to some other planets in our galaxy. The fastest planet ever discovered was found in 2013 by NASA’s Kepler Space Telescope. Named Kepler-78b, it orbits its star at a distance of only 900,000 miles. For comparison, Mercury orbits the Sun at a distance of 36 million miles. With very little space between Kepler-78b and its parent star, the planet orbits its Sun at extreme speeds. It takes a mere 8.5 hours for Kepler-78b to complete one orbit around its star. Imagine living on a planet where a year is only 8.5 hours. As of yet, no other planet has been found with a shorter orbital period, making Kepler-78b the fastest known planet in the universe. 

The Fastest Known Star

It may not seem like it from our perspective here on Earth, but the Sun is actually speeding through space. Like the planets that orbit the Sun, the Sun is in orbit around the center of the Milky Way Galaxy. At this moment, the entire solar system is moving through space at 448,000 miles per hour. That may seem fast, but it takes the Sun 230-million years to complete one orbit because of how gigantic the Milky Way Galaxy is. Compared to some other stars out there, our Sun is relatively slow. The fastest known star in the universe exists near the very center of the Milky Way. Called US-708, it has been measured moving at a speed of 2.7-million miles per hour. When scientists first uncovered US-708 and measured its velocity, they believed it was in orbit around a black hole. The gravitational pull of the black hole would be so strong that it would have accelerated US-708 to tremendous speeds. However, subsequent observations revealed that US-708 might have actually been propelled to its current speed by an exploding star. US-708 was once part of a binary star system, wherein its companion star eventually exploded in a supernova. The resulting explosion was so energetic that it propelled US-708 to become the fastest known star in the universe. 

The Fastest Human-Made Object

We have talked about what some of the fastest things in the universe are, yet how does humanity compare? What’s the fastest thing humans have ever created? As one might expect, the fastest human-made objects are generally spacecraft. Currently, the fastest human-made spacecraft is the Parker Solar Probe, a spacecraft launched by NASA in 2018 to fly closer to the Sun than any spacecraft before it. When NASA launched the Parker Solar Probe, it reached a velocity of 39,500 miles per hour. On its way to the Sun, the Parker Solar Probe conducted repeated flybys of the planet Venus to increase its velocity, using what’s called a gravity assist. As of February 2020, the Parker Solar Probe has become the fastest human-made object in history, reaching a velocity of 330,000 miles per hour. That’s fast enough to circle the Earth 13 times per hour! For humanity, this is truly a remarkable accomplishment. However, even at this speed, the Parker Solar Probe has only achieved 0.05% light speed.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
