Was That a Dropped Call From ET? - The New York Times

Nobody believes it was ET phoning, but radio astronomers admit they don't have an explanation yet for a beam of radio waves that apparently came from the direction of the star Proxima Centauri.

"It's some sort of technological signal. The question is whether it's Earth technology or technology from somewhere out yonder," said Sofia Sheikh, a graduate student at Pennsylvania State University leading a team studying the signal and trying to decipher its origin. She is part of Breakthrough Listen, a $100 million effort funded by Yuri Milner, a Russian billionaire investor , to find alien radio waves. The project has now stumbled on its most intriguing pay dirt yet.

And here's another article:

BLC-1 probably isn't an extraterrestrial signal.

On Dec. 18, the world learned that Breakthrough Listen, a privately funded search for extraterrestrial intelligence, had found its first official candidate signal. The signal's existence lit up the Internet. Was BLC-1, as it's called, finally our moment of contact?

Now, however, the long desert of opportunity may finally be giving way to a new era of growth. In 2015, Internet billionaire Yuri Milner pledged $100 million to create Breakthrough Listen , a next-generation radio-based search for extraterrestrial intelligence.

UFOs, cyberattacks, McCarran airport name change among big 13 Investigates stories in 2020

LAS VEGAS (KTNV) — This year will be remembered largely for the pandemic that has dominated headlines but several other key stories by 13 Investigates in 2020 were among the most read and viewed online.

In April, the Pentagon released perhaps the clearest images yet of a possible UFO in the skies above Earth.

UFOs: Hoping for the Proof | SETI Institute

Is it vindication at last? The New York Times has recently reported that a supposedly canceled Pentagon project to investigate strange aerial phenomena is still showing a pulse. The clandestine effort, originally known as the Advanced Aerospace Threat Identification Program, was said to have ended in 2012. But, apparently, it's still doing its thing under the auspices of the Office of Naval Intelligence.

So, where there's smoke, there's fire, right? If the feds are still forking over tax dollars to delve into odd goings-on in the sky, it must be because they've got convincing evidence for extraterrestrial visitors. At least that's the hope of the 100 million Americans who seem willing to swear on the Good Book that UFOs are, at least in some cases, alien craft.

A UFO — or unidentified flying objects — is an unknown object in the sky. When people talk about UFOs, they’re mostly talking about flying saucers that people believe come from other planets.

Back in May, The New York Times reported that Navy fighter pilots had strange encounters with mysterious flying objects eight times between 2013 and 2019. According to the reports, the fighter pilots and other military officials couldn’t explain where the flying objects had come from.

While 2020 was a challenging year for the space industry (and everyone else) amid the coronavirus pandemic, a bunch of exciting missions that will launch or arrive at their destination in 2021 continued to move forward.

From Mars to asteroids, robots, humans and much more, we'll see space exploration continue to expand across the solar system. We'll also see some new rockets take flight from companies like Firefly Aerospace and Relativity Space.

This may worth something:

How Far Could A Spaceship Go If We Never Ran Out Of Thrust?

A multistage rocket that lost and jettisoned mass as it moved faster and faster would be required to ... [+] reach speeds approaching the speed of light, like the Super Haas rocket shown here. You must either posses a super-efficient type of fuel or gather more fuel along your journey to achieve relativistic speeds. In theory, a ship with constant acceleration could take us farther into the Universe than anything else we've hitherto envisioned.

Right now, there are only three things limiting how far our spacecrafts can take us in the Universe: the resources we devote to it, the constraints of our existing technology, and the laws of physics. If we were willing to devote more resources to it as a society, we have the technological know-how right now to take human beings to any of the known planets or moons within the Solar System, but not to any objects in the Oort cloud or beyond.

Editorial: Space exploration is surging, as are Earthly rivalries - SFChronicle.com

For many people, space travel is better contemplated than attempted. It’s costly, dangerous and nonessential. There are more problems to solve down here than up there. Dream about the heavens by all means, but please skip the risky rocket trip into the unknown.

That view, it’s safe to say, is going nowhere. More than any time since the Cold War space race in the 1960s, this planet is gripped by a wide-open contest to study and sample this solar system and beyond. Space exploration is more popular than ever.

Elon Musk reveals plan to catch SpaceX rockets on launchpad so they can set off again in an hour

SpaceX is planning to be able to catch rockets on their launchpads so they can take off again within an hour, Elon Musk has said.

The proposal would mean the Super Heavy rockets, which are currently in development, would fall back down to Earth and be caught by the launch tower arm that holds the rockets up before they take off.

Mr Musk revealed the plan as he reiterated his idea that the ultimate mission of SpaceX is to build around "1,000 Starships to create a self-sustaining city on Mars".

BREVARD COUNTY, Fla. – Elton John might have said it best in his iconic song "Rocket Man" – "Mars ain't the kind of place to raise your kids."

More than 50 years after we sent humans to the moon – the closest celestial body to Earth – the plan is still to head to Mars , something many astronauts who have flown in space thought we would have already accomplished.

But despite the fact humankind has been unable to send anyone to another place in the universe besides the moon, there are still many with the hopes and expectation that we will become a multi-planetary species in the near future, starting with our red next-door neighbor.

Bad Astronomy | Methane on Mars? New observations show no indication of it.

It was first seen by ground-based observations of Mars back in the 2000s, then subsequently by spacecraft orbiting the Red Planet . But these observations barely detected it, and have been called into question time and again. There's been much debate, and some of the claims have been contradictory. No truly convincing observation of it has been made.

So the European Space Agency sent a probe to Mars called the ExoMars Trace Gas Orbiter, equipped with a device on it called the Nadir and Occultation for MArs Discovery , or NOMAD * . It can look for many different gases, including methane, in the Martian atmosphere in a variety of ways.

A Black Hole in the Milky Way Seemingly Changed the Color of Nearby Stars - IGN
Publisher: IGN
Twitter: @IGN
Reference: (Read more) Visit Source



Ask Astro: What would happen if NGC 6240's three supermassive black holes merged?

A: When two supermassive black holes finally merge, their million-year-long orbital dance culminates with an incredible burst of gravitational waves. If this takes place in the core of a galaxy, it can have dramatic effects on the environment. The gravitational radiation can deposit energy into the surrounding gas, heating it up and making it glow in infrared light for tens of thousands of years.

* * *

However, the gravitational forces of a third body can have lasting effects on a supermassive black hole pair. For example, the pair’s orbit can become highly eccentric, which speeds up the merger through enhanced emission of gravitational waves. In fact, the presence of a third supermassive black hole is believed to play a crucial role in making supermassive black hole mergers possible at all.

Supermassive Black Hole in Centre of Milky Way May Have Caused Changes in Other Stars, Study Finds

A few stars in the Milky Way Galaxy have undergone a change in their colour due to a supermassive black hole right in the centre of the galaxy, reveals a recent research. Our galaxy is home to many stars and some of those include red giants which are luminous ones that are larger and cooler than expected.

In a paper published online in the Astrophysical Journal , astrophysicists have come up with a theory saying that the supermassive black hole, Sagittarius A* launched a powerful jet of gas that took away the red giants' outer layers. There are millions of stars, 1.6 light-years of Sagittarius A*. However, scientists observed that it has fewer red giant stars than expected.

The Moon will appear full for about three days around this time, from Monday evening through Thursday morning.

In the 1930's the Maine Farmer's Almanac began publishing "Indian" names for the full Moons, tying these names to the European months.

Observations from NASA show that the asteroid is zooming through the solar system at an astonishing 3.7 kilometres per second - or more than 13,000 kilometres per hour.

While that may seem an almost incomprehensible speed, it is actually relatively slow for a space rock.

Asteroid News: $10 Quintillion Space Rock [Infographic]

Psyche was discovered back in 1852. It's one of the many objects in the asteroid belt just past Mars and it draws a little extra attention because it is much shinnier than the objects around it. Most asteroids are made of mostly rock and ice which can be somewhat boring. But an asteroid that is almost completely made of metal raises a few questions. 

Since its discovery scientists have wondered how an object like this could form. The current theory is that Psyche is a planetary core that never formed a planet. It was in the process of attracting material when it collided with other objects that knocked all the rocky material off its surface and delayed the planet-forming process.

Meteoric evidence for a previously unknown asteroid: Mineralogy points to large, water-rich

A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago. The composition of a piece of the meteorite Almahata Sitta (AhS) indicates that its parent body was an asteroid roughly the size of Ceres, the largest object in the main asteroid belt, and formed in the presence of water under intermediate temperatures and pressures.

"Carbonaceous chondrite (CC) meteorites record the geological activity during the earliest stages of the Solar System and provide insight into their parent bodies' histories," said SwRI Staff Scientist Dr. Vicky Hamilton, first author of a paper published in Nature Astronomy outlining this research. "Some of these meteorites are dominated by minerals providing evidence for exposure to water at low temperatures and pressures.

Almahata Sitta Meteorites Came from Ceres-Sized Asteroid, Study Shows | Planetary Science, Space

The parent body of the Almahata Sitta meteorites — space rocks that rained down on the Nubian Desert in Sudan in 2008 — is a 640 to 1,800 km-wide water-rich asteroid that is as yet unknown, according to new research.

Hamilton et al . studied the composition of Almahata Sitta 202 to determine that it likely originated from a previously unknown parent asteroid. Image credit: Hamilton et al ., doi: 10.1038/s41550-020-01274-z.

In October 2008, a 4.1-m-diameter fragment of a carbonaceous chondrite asteroid entered Earth's atmosphere and exploded 37 km above the Nubian Desert.

Asteroid treasure, COVID vaccine and public peer review

Hayabusa2 collected the samples during a year and a half of poking and prodding Ryugu — a small asteroid shaped like a squashed sphere, peppered with giant boulders. Ryugu is a C-type, or carbon-rich, asteroid, which scientists think contains organic and hydrated minerals preserved from as far back as 4.6 billion years ago. The samples could help to explain how Earth became covered with water.

"The samples containing precious asteroid material will provide scientists with key information about the formation of the Solar System," says Ed Kruzins, director of the Canberra Deep Space Communication Complex at the Commonwealth Scientific and Industrial Research Organisation, which helped to track the spacecraft and its encounter with the asteroid.

Mysterious asteroid fragment is a time capsule from the early solar system

Back in 2008, a meteorite later named Almahata Sitta (AhS) crash-landed in Sudan. Now scientists have taken another look at this meteorite and believe it was part of a monster 9-ton meteor that exploded into 600 pieces in the atmosphere, and that meteor was probably hurled over here by an even more enormous asteroid. It's almost as if it flung a piece of the nascent solar system right at our planet.

Carbonaceous chondrites are also thought to be one source of the water that made it over here when things were smashing into each other in the chaos that was the early solar system 4.6 billion years ago. So are comets, basically huge balls of ice shooting through the void.
