Alien life might thrive on the moons of these 121 giant planets

  Alien life might thrive on the moons of these 121 giant planets Moons orbiting huge exoplanets may be even better places to live than Earth, scientists say. But there's a catch.An international team of scientists has identified 121 gas giant planets, each at least three times more massive than Earth, that orbit in the habitable zones of their stars and are each expected to play host to several large moons.

The Moon , Earth's natural satellite, seems to hover in the sky , unaffected by gravity. The solar system is full of satellites. Earth has many satellites, including the natural Moon as well as artificial satellites placed in orbit for Why doesn't the Moon hit Earth even though it is " falling " toward it?

Weather could be the culprit. High-altitude hail or lightning might have hit the birds, which caused them to fall from the sky . The only problem is the birds don't seem to have any of the telltale bruises or injuries that a weather-related explanation would cause.

“These people are not in danger.”

So begins NASA’s explanation of a stunning video published June 1, which shows a monster moon quickly approaching a dozen or so humans perched on a ridge. Just as rapidly, the looming lunar orb then starts to sink behind the ridge, looking for all the world as if it is falling from the sky.

Why, you might ask, is NASA getting so excited about a sci-fi movie clip, or some internet illusion created with a dash of editing skulduggery? Spoiler: They’re not.

Daniel López, a photographer based in the Canary Islands, shot this scene on the morning of May 30 from a perch near Tenerife’s Mount Teide volcano, capturing the otherworldly landscape as the sun rose and the full moon set. (The first of its kind for the month of May, this particular full moon is traditionally known as the flower moon, corn planting moon, or milk moon by various cultures, in case you’re curious.)

Japan, South Korea spar on engaging Kim Jong Un in dialog

  Japan, South Korea spar on engaging Kim Jong Un in dialog Japan's Defence Minister Itsunori Onodera said on Saturday it was important not to reward North Korea for only agreeing to dialog and it must take concrete action to dismantle all of its nuclear and ballistic missile programs. His South Korean counterpart urged support for dialog to help North Korea join the international community, saying its leader Kim Jong Un must be given the benefit of the doubt.The apparent divergence of views between the U.S. allies come ahead of a planned summit between Kim and U.S. President Donald Trump on June 12 in Singapore to discuss ending the North's nuclear weapons program.

You can see that the moon has hundreds of shallow holes on it made by rocks which fell from space. Have you ever wondered why the sun seems to be moving in the sky ? When the moon has made one complete circle around Earth, it too, has made one full revolu-tion.

So the Ponzo Illusion kicks in: your brain sees the Moon as being huge , and it looks like you could fall into it. The Illusion works for the Sun, too. In fact, years ago I saw Orion rising over a parking lot, and it looked like it was spread across half the sky .

The resulting video is real and unaltered—and it’s a great illustration of how science can play tricks on us.

First, the reason for the moon’s seeming humongousness is surprisingly simple. López used a telephoto lens to capture the scene, which can dramatically compress the apparent distance between objects in the foreground and those in the background. This is a very common effect in photos of whales far off the California coastline, which often appear to be breaching within several feet of the shore.

In this particular shot, the mini-humans are perched atop a volcano roughly 10 miles away. Our celestial companion is really about 240,000 miles behind them, positioned so that its fully illuminated disk perfectly frames the volcano’s summit.

As for why the moon appears to move so quickly, that’s the result of Earth’s rotation and not a trick of time-lapse photography or an accelerated video playback.

Spinning at about a thousand miles an hour, Earth’s perpetual pirouetting is normally imperceptible to those of us on the surface, except when we stare for a long while at objects in the sky and or shadows on the ground. Once again, the extremely compressed distance in these images both illuminates the rate at which our planet twirls and accentuates the size of Earth’s lunar friend.

Woman Says Neil Armstrong Gave Her A Vial Of Moon Dust, Sues NASA To Keep It .
The space agency hasn't confiscated the dust, but it has reportedly seized lunar materials from citizens before.Laura Cicco said Armstrong was a family friend, and that her mother gave her a tube of priceless lunar particles when she was 10, along with a note that read: “To Laura Ann Murray — Best of Luck — Neil Armstrong Apollo 11.
