Fireball across North Carolinian Sky

See the source image

On September 24, NASA Meteor Watch reported that residents in North Carolina reported seeing at least 5 fireballs, with over 80 eyewitnesses reporting the view. The event occurred at 7:40 PM EST. Upon analysis, NASA confirmed the fireballs as meteor skimming across the coast of North Carolina and had become visible due to its proximity: 48 miles above the ocean off Camp Lejeune. The fireballs were noted to be moving at 32,000 miles per hour and disintegrated just 28 miles above Moorehead City. The fireballs did not make it past the Earth’s atmosphere.

The American Meteor Society posted a video on Youtube showing the fireball meteor in the sky.

Meteoroids usually enter Earth’s atmosphere at 25,000 to 160,000 mph, but most do not maintain that speed due to the Earth’s thick atmosphere. As was the case here, the meteors had burned out before it could even reach the ground.

Fireball is not just any old term either; it is considered to be “exceptionally bright” meteors that appear brighter than planet Venus, bright enough to be observed by “ground-based observers” such as the 80 or so witnesses in North Carolina.

AMS explained that every day, Earth sees several thousand fireball meteors, but most of them tend to take place over oceans and unpopulated regions.

Hazardous Asteroid Bennu Will Approach Earth before 2300

A Hazardous asteroid named Bennu will approach Earth between now and the year 2300. According to NASA, in a study titled “Ephemeris and hazard assessment for near-Earth asteroid (101955) Bennu based on OSIRIS-REx data,” it stated that “NASA researchers used precision-tracking data from the agency’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer(OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists’ ability to determine the total impact probability and predict orbits of other asteroids.”

This study was published in a journal named “Icarus,” and Kelly Fast, the program manager for the Near-Earth Object Observations Program at NASA Headquarters in Washington DC said, “NASA’s Planetary Defense mission is to find and monitor asteroids and comets that can come near Earth and may pose a hazard to our planet,” and “We carry out this endeavor through continuing astronomical surveys that collect data to discover previously unknown objects and refine our orbital models for them. The OSIRIS-REx mission has provided an extraordinary opportunity to refine and test these models, helping us better predict where Bennu will be when it makes its close approach to Earth more than a century from now.”

In 2135, asteroid Bennu will make a close approach to Earth but it probably will not be too dangerous to our planet at that time, because during the encountering, Earth’s gravity will be altered.

The total impact of the Bennu asteroid through the year 2300 is about 1 in 1,750 (or 0.057%), and the researchers were able to identify Sept. 24, 2182, as the most significant single date in terms of a potential impact probability of 1 in 2,700 (or about 0.037%). Bennu is one of the two most hazardous asteroids in the solar system with 1950 DA. The Bennu’s chance of hitting Earth is very low respectively.

The OSIRIS Rex spacecraft spent more than two years near the Bennu and it has gathered sources and materials from the Bennu such as its size, shape, mass, the sample of rock, the dust from the asteroid’s surface. The spacecraft composed it while monitoring its spin and orbital trajectory. This spacecraft will deliver to Earth all this information and materials on Sept. 24, 2023, for further investigation.

The Bennu asteroid will give us a tremendous opportunity of seeing how the asteroid’s orbits will evolve and the role of “gravitational keyhole” during its 2135 close approach. This keyhole will be located in space if the Bennu would locate on a path toward a future impact on Earth. if the asteroid were to pass through them at certain times, Earth’s gravitational force will be in effect on the asteroid.

Scientist, Farnocchia and his team will calculate the location of Bennu while it approaches and look to whether it might pass through a gravitational keyhole and evaluated various types of small forces that may affect the asteroid as it orbits the Sun.

When the asteroid spins, the Sun heats the Bennu on the dayside and cools down on the nightside as well. As it cools, the surface releases infrared energy that generates a small amount of thrust on the asteroid. This phenomenon is called the Yarkovsky effect. Over the short timeframe, this thrust is small but over the long period of time, the effect on the asteroid’s position builds up and can play a significant role in the asteroid’s path changing.

“The Yarkovsky effect will act on all asteroids of all sizes, and while it has been measured for a small fraction of the asteroid population from afar, OSIRIS-REx gave us the first opportunity to measure it in detail as Bennu traveled around the Sun,” said Steve Chesley, a senior research scientist at JPL and study co-investigator. “The effect on Bennu is equivalent to the weight of three grapes constantly acting on the asteroid – tiny, yes, but significant when determining Bennu’s future impact changes over the decades and centuries to come.” According to NASA.

The Annual Solar Eclipse: Partial Solar Eclipse visible on the sky on June 10, 2021

Eclipse cartographer Michael Zeiler created this detailed visibility map for the June 10, 2021, annular solar eclipse. Skywatchers in much of central and eastern North America, as well as parts of Europe and Africa, will be able to enjoy this event as a partial solar eclipse; the full “ring of fire” effect will be limited to a narrow slice of land in central and eastern Canada. (Image credit: Michael Zeiler, GreatAmericanEclipse.com)

Early in the morning (about 4:40 AM ET) on June 10, we will see the annual solar eclipse which will appear as a partial solar eclipse. According to timeanddate.com, most Northeast U.S. and Canadian residents will see the sky darken after the Sun rises.

The residents will see the “Ring of Fire” like the shape of the eclipse, across central to eastern Canada for at least 390 miles.

“Because the moon will be just 57 hours past apogee, its farthest point from Earth during its orbit, it will appear somewhat smaller than usual – smaller than the apparent disk of the sun. It is for this reason that viewers in the shadow’s center will get an annular (partial) rather than a total eclipse: the sun will become a brilliant ring (annulus) of light encircling the moon’s dark silhouette for several minutes,” said Space.com.

Those living in the Lake Superior region will see the horseshoe-shaped Sunlight when the Sun rises for about 3.5 minutes.

Humongous Space Debris Will Hit Earth on May 9

On April 29, China launched a Long March 5B Rocket, the country’s first new space station into orbit around the Earth. As a result, a huge piece of space junk is set to collide with Earth’s atmosphere this weekend with pieces of debris landing elsewhere on Earth.

The Aerospace Corporation announced on Twitter, “Our latest prediction for CZ-5B Rocket body reentry is: 09 May 2021 03:43 UTC ± 16 hours Reentry will be along [with] one of the ground tracks shown here. It is still too early to determine a meaningful debris footprint.”

(Picture obtained from The Aerospace Corporation’s Twitter page)

Although Chinese officials initially applauded the launch of the 5B Rocket, the core stage which does the heavy lifting to get the space station into orbit initially failed and fell back towards the atmosphere uncontrollably.

About 21 metric tons of debris from space will hit on Earth’s surface but no one knows the exact location and the time.  “Scientists know that space junk will enter Earth’s atmosphere somewhere between approximately 41.5 degrees north latitude and 41.5 degrees south latitude based on the trajectory of the rocket”. according to Accuweather.com, this zone includes some of the world’s largest cities, but it also includes large swaths of the vast Pacific Ocean, Indian Ocean, and the Atlantic Ocean.

This space debris is the world’s largest space junk to fall back onto Earth’s orbit so far, and the worst is that no one knows exactly where it’ll land.

Super Pink Moon Visible Tonight on the Northeast Sky

NASA announced that the first supermoon of the year will be “April 26, 2021, appearing opposite the Sun in Earth-based longitude at 11:32 p.m. EDT. [This will be the next day from the Atlantic Daylight Savings timezone eastward across Africa, Europe, Asia, and Australia.]  Most commercial calendars are based on Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC) and will show this full Moon occurring on Tuesday, April 27, 2021. The Moon will appear full for about three days around this time, from Sunday night through Wednesday morning,” on its Twitter account.

This “Pinkish color” of the supermoon will be the first supermoon of the year, and the second one will be seen on May 26 when it will brighten the sky one more time. The names of this supermoon are “Sprouting Grass Moon, the Egg Moon, and among coastal tribes of North America, the Fish Moon, as this was when the shad swam upstream to spawn,” according to NASA.

The “pink” of the supermoon on April 26 is based on the herb moss pink, which is native to the Eastern United States and known to be the fastest blooming in springtime.

Supermoons seem greater because of the slightly closer distance to Earth. There will be two supermoons this year.

BTS Hits Billboard 100 with a Dynamite #1

After landing with Billboard #4 with the last single “On,” in March, K-Pop boy band BTS debuted with an all-English single, “Dynamite” at the top of the Billboard’s Hot 100.

BTS is the first K-Pop group to lead the Hot 100. Released on August 21, 2020, showed a result of 33.9 million US stream, 300,000 sold, and drew 11.6 million radio airplay audience impressions the week ending August 30.

BTS’ “Dynamite” made the best digital sales since One Direction’s “Drag Me Down” 5 years ago, and marks BigHit entertainment’s first #1 on the Billboard chart. Consultations to BTS!

Of course, much of BTS’ success comes from BTS’ use of technology (mainly YouTube and V Live) to gain followers, interact with them, and establish themselves as serious brands. Many analysts tout that the globalization of Broadband access has made not only information flow throughout the world, but also allow easier means for fans to gain access to their favorite bands’ music and show clips.

Covid-19’s Real Problem: Organ damage

As US sees 150,000 deaths from COVID-19, some of those who are for quick reopening tout the relatively low death percentage rate as an argument against the severity of COVID-19. However, those who are recovering from COVID-19 show something more sinister from coronavirus infection: organ damage.

Two German studies found that many patients recovering from COVID-19 had heart abnormalities that didn’t exist before. The study included 100 patients from the University of Hospital Frankfurt COVID-19 Registry.

1/3 on the registry recovered at the hospital, while the other 2/3 recovered at home; however, in the 78 of the original 100, there were now heart abnormalities, with 60 of them showing inflammation in the heart muscle from COVID-19.

This abnormality would not be found on the echograms more frequently used to detect heart abnormalities.

Such results are quite damaging; those who have this weakness will likely require more extensive treatments and be at risk for abnormal heart beats and other heart problems.

So yes, maybe COVID-19 only kills around 1 percent of those infected; however, the true harm of COVID-19 isn’t necessarily the fast death, but the lasting impact on the majority of those that recover from the disease; mostly, the weakening of the organs in the rest of the body.

SpaceX Places momentous foot in the Sky: “Endeavor” Flies 19 Hours to ISS

Photo from NASA TV

More than 300,000 people gathered nearby to watch the historical launch from the Kennedy  Space Center to the International Space Station on Saturday.

The two NASA astronauts’ family and Vice President Pence attended to bid them good luck.

And on Sunday, Douglas Hurley and Robert Behnken, two NASA astronauts arrived at the International Space Station without any inconvenience, even “succeeding sleep.”

Even with bad weather, including thunderstorms and threat of lightning strikes, could not stop the Endeavour and its astronauts.

After more than 2 months of Coronavirus pandemic stress, racial conflict, and economic turmoil, this was a ray of sunshine many Americans needed.

This Project was started since 2014 between SpaceX, Boeing, and NASA, as a way to establish 20 more years of travel between Earth and space.

SpaceX launched Complex 39A before the launch of a SpaceX Falcon 9 rocket and Dragon spacecraft at the Kennedy Space Center.

Elon Musk and his SpaceX team opened in the middle of Coronavirus pandemic to complete the project. And For the first time in nearly a decade, a space shuttle took off from American soil.

Space Travel Comes Closer to Reality

(Photo from Space X)

SpaceX announced a plan to send 4 private citizens into space for a global trip by either end of 2021 or by early 2022. The price is not yet disclosed, and much of the details remain shrouded; however, SpaceX and its tourist company Space Adventures, plan to fly SpaceX’s Dragon spacecraft and orbit the planet.

Despite Musk’s overly enthusiastic hopes, SpaceX had much delays in getting an astronaut to fly in one of its spaceships, as due to the certifying process. NASA flight is supposed to take place within the year.

There are two other competitions in the private market: Richard Branson’s Virgin Galactic and Jeff Bezos’ Blue Origin. They do not promise as much of an experience as that of Elon Musk’s SpaceX however; Virgin Galactic promises weightlessness for a few minutes, and Blue Origin promises similar amount of time as Virgin Galactic, but in a ship similar to SpaceX’s Dragon.

Regardless, the time continues to inch closer, as humanity attempts for a leap outside of the Earth’s atmosphere. Only time will tell as to who wins.

Message from a lost civilization? Radio Signal from space arrives every 16 days

Earth regularly receives random radio waves from space, due to the dynamic nature of the universe. However, while most radio waves either emit once and never repeat, or sends repetitive fast radio bursts (FRBs) multiple times in sporadic or cluster form, this time, it was different.

Between September 16, 2018 to October 30, 2019, researchers at the Canadian Hydrogen Intensity Mapping Experiment/Fast Radio Burst Project collaboration detected a pattern of radio occurring every 16 or so days. Signal would release a burst or two each hour for a course of 4 days, then going silent for 12 days after.

The finding is available on arXiv and has yet to be peer-reviewed. However, the researchers concluded that the signal came from a massive spiral galaxy about 500 million light years away.

Unfortunately, the exact location of the radio burst has not yet been found, as the researchers could pinpoint multiple locations for the source of radio signals.

Authors of another research paper believe it could be from a neutron star, one of the smallest stars and remnants of supernovae, interacting with another star in a binary system.

As it turns out; scientists do not believe that it comes from another extraterrestrial civilization; however, it reveals an important aspect of reality unobserved.
