Interstellar visitor ’Oumuamua probably came from a two-star system – Alien UFO Sightings

Astronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1(’Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighbourhood.

The certainty of its interstellar origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.

Its name comes from a Hawaiian term for messenger or scout. Indeed, it is the first space rock to have been identified as forming around another star. Since asteroids coalesce during the process of planet formation, this object can tell us something about the formation of planets around its unknown parent star.

The latest analyses with ground-based telescopes show that ’Oumuamua is quite similar to some comets and asteroids in our own solar system. This is important because it suggests that planetary compositions like ours could be typical across the galaxy.

It is thought to be an extremely dark object, absorbing 96% of the light that falls on its surface, and it is red. This colour is the hallmark of organic (carbon-based) molecules. Organic molecules are the building blocks of the biological molecules that allow life to function.

It is widely thought that the delivery of organic molecules to the early Earth by the collision of comets and asteroids made life here possible. ’Oumuamua shows that the same could be possible in other solar systems.

Its characteristics have been published by two independent groups of astronomers. The first group, led by Karen Meech, University of Hawaii, also found that ’Oumuamua was extremely elongated and roughly 400 metres long. Using the European Southern Observatory’s Very Large Telescope(VLT) they also found that it rotated once every 7.3 hours.

The other group of astronomers, led by David Jewitt, University of California Los Angeles, estimated how many other interstellar visitors like it there might be in our solar system.

Surprisingly, they calculate that another 10,000 could be closer to the sun than the eighth planet, Neptune, which lies 30 times further from the sun than the Earth. Yet these are currently undetected.

Each of these interstellar interlopers would be just passing through. They are travelling too fast to be captured by the gravity of the sun. Yet it still takes them about a decade to cross our solar system and disappear back into interstellar space.

If this estimate is correct, then roughly 1,000 enter and another 1,000 leave every year – which means that roughly three arrive and three leave every day.

Using robotic telescopes such as Pan-STARRS, the one that detected ’Oumuamua, to look for asteroids is a priority for astronomers as they concentrate on discovering potentially hazardous objects that could impact Earth.

Imminent upgrades to these survey telescopes and improvements in data processing techniques mean that astronomers will soon be able to detect smaller and fainter objects. They expect a number of these to be interstellar interlopers like ’Oumuamua.

Why the world’s top UFO researchers chose Tom DeLonge as their mouthpiece – Alien UFO Sightings

As if we needed more proof that we’re living in the strangest of times, Blink-182 guitarist Tom DeLonge, a man who once wrote a (pretty great) song called “Dick Lips,” has proven himself to be a galvanizing force in the realm of extraterrestrial exploration. Sure, we all had a laugh when DeLonge quit the band and started crowdfunding for a spaceship, but then WikiLeaks revealed he was chatting UFOs with high-ranking political consultant John Podesta and a New York Times report not only confirmed some of DeLonge’s previous ramblings on the subject, but also the legitimacy of some of those involved in his To The Stars Academy.

To listen to DeLonge speak on the subject is, to say the least, maddening. He’s articulate in outlining the aims of his academy, and his stories as to how he first came in contact with the government remain remarkably consistent, but, as so happens in this sprawling interview with Joe Rogan, it isn’t long before DeLonge starts spouting off about Greek culture and the lost city of Atlantis and we’re back to rolling our eyes.

If you’re in need of a primer on the whole situation, as well as a breakdown of the ambitious science-cum-entertainment plan of To The Stars, The Fader has published a pretty exhaustive rundown. You’ll also read about the encounter that confirmed DeLonge’s belief in aliens and, surprise, it happened while he was camping near Area 51.

Probably the most revealing part of the piece, however, is the reaction from the greater UFO community, who aren’t surprised at all that DeLonge has been chosen as the effort’s mouthpiece. “It might seem odd to some people that Tom DeLonge has built up this impressive team of scientists and former government insiders, but it doesn’t surprise me,” says Nick Pope, who used to study UFOs for the British government. “People do get starry-eyed, especially if your whole career has been about secrecy and silence. A rockstar is the absolute antithesis of that, and so it’s appealing.”

The International UFO Congress’ Alejandro Rojas agrees. “[DeLonge is] able to get people to open up and talk with him. This is a cool guy you want to hang with and you want to be buddies with.”

You can even see the team’s starry eyes in their own quotes to The Fader. Luis Elizondo, who ran the government’s secret UFO investigation program that was the subject of the aforementioned Times article, says, “Forgive the cliché, but this is really a rockstar team.”

Ancient Egyptian Pharaoh May Be the 1st Known ‘Giant’ – Alien UFO Sightings

The supposed remains of Sa-Nakht, a pharaoh of ancient Egypt, may be the oldest known human giant, a new study finds.

Myths abound with stories of giants, from the frost and fire giants of Norse legends to the Titans who warred with the gods in ancient Greek mythology. However, giants are more than just myth; accelerated and excessive growth, a condition known as gigantism, can occur when the body generates too much growth hormone. This usually occurs because of a tumor on the pituitary gland of the brain.

As part of ongoing research into mummies, scientists investigated a skeleton found in 1901 in a tomb near Beit Khallaf in Egypt. Previous research estimated that the bones dated from the Third Dynasty of Egypt, about 2700 B.C.

Prior work suggested that the skeleton of the man — who would have stood at up to 6 feet 1.6 inches (1.987 meters) tall — may have belonged to Sa-Nakht, a pharaoh during the Third Dynasty. Previous research on ancient Egyptian mummies suggested the average height for men around this time was about 5 feet 6 inches (1.7 m), said study co-author Michael Habicht, an Egyptologist at the University of Zurich’s Institute of Evolutionary Medicine.

Ancient Egyptian kings were likely better fed and in better health than commoners of the era, so they could be expected grow taller than average. Still, the over-6-foot-tall remains the scientists analyzed would have towered over Ramesses II, the tallest recorded ancient Egyptian pharaoh, who lived more than 1,000 years after Sa-Nakht and was only about 5 feet 9 inches (1.75 m) tall, Habicht said.

In the new study, Habicht and his colleagues reanalyzed the alleged skull and bones of Sa-Nakht. The skeleton’s long bones showed evidence of “exuberant growth,” which are “clear signs of gigantism,” Habicht said.

These findings suggest that this ancient Egyptian probably had gigantism, making him the oldest known case of this disorder in the world, the researchers said. No other ancient Egyptian royals were known to be giants.

“Studying the evolutionary development of diseases is of importance for today’s medicine,” Habicht said.

In the early dynasties of Egypt, short statures were apparently preferred, with “many small people in royal service,” Habicht said. “The reasons for this preference are not always certain.”

Still, because the alleged remains of Sa-Nakht were buried in an elite tomb, there may have been no social stigma attached with gigantism at the time, the researchers said.

The scientists detailed their findings in the August issue of the journal The Lancet Diabetes & Endocrinology.
