Harvard Astronomy Professor Says Aliens Visited Earth in 2017

“The realization that we are not alone will have dramatic implications for our goals on Earth and our aspirations for space.”

Avi Loeb, an astronomer who holds the chair of Harvard University’s Astronomy Department, is set to publish a book with the title “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.”

In the book, Loeb further pushes his controversial theory that Oumuamua, an interstellar object spotted by astronomers in 2017, may in fact be an alien probe that was sent by an advanced extraterrestrial civilization.

According to a statement by Loeb’s publisher HMH Books given to the Boston Globe, Loeb “showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake.”

To Loeb, this object is evidence that an advanced alien civilization visited us in 2017. It’s a fascinating theory, but one that separates him from other SETI researchers, who firmly believe that we have not yet found any proof of life beyond the Earth.

However, Oumuamua is the first interstellar object to have ever been directly observed. It was first spotted by astronomers at the Haleakalā Observatory, Hawaii, on October 19, 2017.

“Honestly, I think it’s a bit of wild speculation,” Canadian astronomer Robert Weryk, who himself discovered ‘Oumuamua in 2017, told the CBC in 2018. “We actually think that’s not true based on the data that we obtained.”

In 2019, an international team of researchers published a study on ‘Oumuamua in the journal Nature Astronomy, contending that they found “no compelling evidence to favor an alien explanation,” and that “Oumuamua’s properties are consistent with a natural origin.”

The researchers argued that while the object didn’t quite fall under the definition of either an asteroid or comet, small gas emissions from its surface could explain its unusual trajectory through the solar system, deviating from an expected path that took the Sun’s gravitational pull into account.

Although, Oumuamua appeared to have been gaining momentum, as though it were being propelled by some kind of “peculiar propulsion system” according to another study that TMU previously reported.

That study was conducted in 2018 by Harvard professor Avi Loeb and Harvard postdoctoral Shmuel Bialy, the pair suggested that the object “may be a fully operational probe sent intentionally to Earth’s vicinity by an alien civilization.”

Despite the criticism, Loeb believes strongly that ‘Oumuamua could be a sign that we’re not alone in the universe.

“The data we gathered on ‘Oumuamua are incomplete,” he argued in a recent December essay for Scientific American.

“To learn more, we must continue to monitor the sky for similar objects,” he wrote. “The realization that we are not alone will have dramatic implications for our goals on Earth and our aspirations for space.”

Exotic “Blue Jet” Lightning Shooting From Electrical Storm Captured by Space Station

State-of-the-art equipment on the International Space Station (ISS) has captured a brilliant view of a thunderstorm from above, including a clear view of a strange type of lightning known as a blue jet.

The footage could help us better understand how lighting originates and even how storms distribute greenhouse gases in the Earth’s atmosphere, offering important pointers on weather systems in general.

However, the footage also offers a damned cool perspective of electrical storms that we’ve never enjoyed until now.

In video released by the European Space Agency that was captured in February 2019, blue-colored lightning bolts can be seen shooting upwards from storm clouds over the Pacific island of Nauru into the highest reaches of the stratosphere.

Blue jets are types of lightning that shoot upwards from thunderclouds into the stratosphere, striking altitudes exceeding 30 miles (50 km) in under a second. While our typical lightning interacts with a mixture of gases in the lower atmosphere to create glowing white bolts, blue jets excite stratospheric nitrogen to create a luminous blue hue.

While the phenomenon has long been observed from aircraft and ground-level vantage points, the European Space Agency’s Atmosphere-Space Interactions Monitor (ASIM) at the ISS, which is about 250 miles (400 km) above the Earth, have enabled researchers to get the best glimpse yet of a blue jet arising from a sudden burst of electricity emanating from the top of a thundercloud, according to research published Wednesday in the scientific journal Nature.

“Elves,” or rapidly-expanding rings of optical and UV emissions, were also generated by the flash. The emissions, which took place at the bottom of the ionosphere, were a result of the interaction between electrons, radio waves, and the atmosphere.

Blue jets and elves, like other upper-atmospheric phenomena such as mythological-sounding sprites, are important to our understanding of how radio waves travel through the air, with potential ramifications on our communications technologies as well as the more fundamental questions of how lightning is initiated in our clouds and how greenhouse gases are concentrated in the atmosphere.

However, spotting these brilliant light shows has been difficult for earthbound observers. Yet the highly sensitive tools installed on the Space Station in 2018 – including photometers, optical cameras, and an X- and gamma-ray detector –were able to capture the elusive phenomena.

The knowledge gleaned from the footage could prove crucial to researchers finally making sense of the processes unfolding in the upper atmosphere.

“This paper is an impressive highlight of the many new phenomena ASIM is observing above thunderstorms and shows that we still have so much to discover and learn about our Universe,” said Astrid Orr, the Physical Sciences Coordinator for human and robotic spaceflight at the European Space Agency.

“Congratulations to all the scientists and university teams that made this happen as well as the engineers that built the observatory and the support teams on ground operating ASIM—a true international collaboration that has led to amazing discoveries,” Orr added.

Advocates Hail Biden Executive Order on LGBTQ Rights as the Most Far-Reaching in US History

Published

on

Civil rights advocates on Wednesday applauded President Joe Biden for signing an executive order on his first day in office bolstering anti-discrimination protections for LGBTQ people after years of attacks and rollbacks during the Trump administration, and for signaling that he will move to reverse his predecessor’s ban on transgender people serving in the U.S. military.

“Every person should be treated with respect and dignity and should be able to live without fear, no matter who they are or whom they love,” the order begins.

The order continues:

Children should be able to learn without worrying about whether they will be denied access to the restroom, the locker room, or school sports. Adults should be able to earn a living and pursue a vocation knowing that they will not be fired, demoted, or mistreated because of whom they go home to or because how they dress does not conform to sex-based stereotypes. People should be able to access healthcare and secure a roof over their heads without being subjected to sex discrimination. All persons should receive equal treatment under the law, no matter their gender identity or sexual orientation.

“It is the policy of my administration to prevent and combat discrimination on the basis of gender identity or sexual orientation, and to fully enforce Title VII and other laws that prohibit discrimination on the basis of gender identity or sexual orientation,” the order states. It goes on to direct the heads of each federal agency to ensure adherence to these principles and to develop plans to implement changes where necessary. 

The Human Rights Campaign (HRC) hailed Biden’s order as “the most substantive, wide-ranging executive order concerning sexual orientation and gender identity” in U.S. history. 

HRC president Alphonso David issued a statement declaring that “today, millions of Americans can breathe a sigh of relief knowing that their president and their government believe discrimination based on sexual orientation and gender identity is not only intolerable but illegal.” 

Biden’s order gives teeth to Bostock v. Clayton County, the June 2020 U.S. Supreme Court ruling which declared that sexual orientation and gender identity discrimination are prohibited under Title VII of the Civil Rights Act. The executive order also stands in stark contrast to the past four years, a period during which LGBTQ people saw their rights repeatedly eroded and, in the case of transgender people, their very existence as human beings challenged

Mara Keisling, executive director of the National Center for Transgender Equality, said in a statement that “on his very first day in office, President Biden is stating clearly that there is no place for discrimination in the federal government.”

Bostock v. Clayton County was a major victory for LGBTQ Americans,” added Keisling. “Today’s executive order moves us another step toward a day when transgender people can openly live as who they are without being targeted for discrimination.”

In one particularly egregious rights rollback, the Trump administration banned transgender people from serving in the U.S. military. On Wednesday, White House Press Secretary Jen Psaki said that Biden will soon turn the page on this dark chapter in civil rights history. Ending the trans ban, said Psaki, will be among the “additional executive actions” the president will take “in the coming days and weeks.”

Blake Dremann, a transgender rights advocate and active-duty Navy lieutenant commander, told NBC News that trans people are “excited for the ban to be lifted” and the day when “we never have to tell another service member that being their authentic selves is a barrier to serving their nation.”

“The resilience and success of trans service members has shown we are committed to the success of the nation,” said Dremann.

The Moon, Mars and Uranus Will “Meet” in an Ultra-Rare Conjunction Tonight

Elias Marat

Published

on

Last month, stargazers were treated to a rare “Christmas star” that saw Jupiter and Saturn aligned so closely that they appeared to be on a collision course with one another.

And this week, we will be treated to another rare and spectacular space event.

According to astronomers, over the next few nights Mars, Uranus and the Moon will come in remarkably close proximity in our skies, with Mars passing 1.75 degrees to the north of Uranus while also sharing the scene with the Moon, reports EarthSky.

The infrequent occasion will look best on Thursday evening, just after dusk through just after midnight in the eastern United States, when the Moon and the two planets will appear very close along the southwest horizon.

For those in the U.K., the meeting will happen at roughly 4:43 p.m. but when the sky turns dark, the planets will reach their highest point at roughly 6:06 p.m. before remaining visible until about 12:36 a.m.

Mars, which is the fourth planet from the Sun, will be especially luminous as it stands out from the stars and will lie just above the Moon.

Uranus, however, may appear as a somewhat faint dot. However, the vertical alignment of the three planets should allow us to see all three of the planets with Uranus shining somewhat dimly between the Moon and Mars.

“Uranus will be about 1.5 degrees down and to the left of Mars but will not be visible to the naked eye,” Dean Regas, the astronomer for the Cincinnati Observatory, told local12. “You will need binoculars or a telescope to see it since it is almost 2 billion miles away.”

As EarthSky reported, Mars has been increasingly dimmed over the course of the last several months while the Earth has rushed ahead of it in our much more rapid and smaller orbit around the sun.

However, Mars is still shining brilliantly like some of the brightest stars in our skies. If the skies are clear, Mars will be easily visible as a bright, shining celestial object in the vicinity of the Moon.

Uranus, which is the seventh planet from the sun lying at a distance of roughly 1.8 billion miles (2.9 billion km) away, will be extremely faint – more than 150 times fainter than the Red Planet.

The planet, which is about four times wider than our home planet – making it the size of a basketball if the Earth were an apple, according to NASA – is the outermost of the planets in our solar system that still remains visible with the naked eye.

However, given that seeing it with the eye requires extremely dark skies, the fact that the moon will be shining – in close proximity, no less – means that stargazers will definitely need binoculars or even a telescope to catch a full glimpse of the rare “meeting.”

“The interesting news is that Mars and Uranus are close together on the sky’s dome, so that – theoretically – you could see Mars and Uranus in a single binocular field of view for the next week or so, if the moon weren’t in the way,” EarthSky added.

So get your binoculars ready, and enjoy!
