Apollo moon rocks shed new light on Earth's volcanoes

Apollo moon rocks shed new light on Earth's volcanoes

According to, a lunar eclipse happens when the full moon passes through Earth's shadow as it orbits on the opposite of the planet from the Sun.

The eclipse coincides with the 50th anniversary of the Apollo 11 launch, which took the first men to the moon. It will miss North America except for the most eastern and southern parts of the continent.

On Tuesday night, there was a full moon - Thunder has glowed brightly.

During a lunar eclipse, we can see Earth's shadow on the moon.

In Australia and Asia, the eclipse was visible in the early hours of Wednesday morning and, in Europe, it was visible on Tuesday evening as the sun went down.

The magnitude of the eclipse, which refers to the maximum percent of the moon's diameter immersed within Earth's umbral shadow, will be 65 percent.

So, the moon may be rusty red tonight, or a less exciting dark grey - depending on conditions.

Iran has said that it is not subject to European Union sanctions. "We must keep control of common sense", he said. Tensions have spiked since U.S.

As well as showing the lunar event itself, astronomer and founder of Astronomy Ireland David Moore will speak at the event and educate those in attendance of how lunar eclipses shaped ancient civilisations, leading to our modern-day fascination. When the Moon is fully covered by Earth's shadow, it is called a full lunar eclipse, but when only a small portion of the moon appears dark due to incomplete overlapping, it is called a partial lunar eclipse.

During a lunar eclipse, the longer wavelength red light can penetrate Earth's atmosphere and reach the moon's surface.

This year, the first new moon of July occurred on July 2 at 3:16 p.m. EST, while the second will take place at 11:12 p.m. on July 31, according to the Old Farmer's Almanac.

When this happens, Earth blocks the light from the sun to the moon.

"You will not see the whole moon disappear, but just enough to make the spectacle worthwhile for stargazers around the country", Dr Tucker said. The Virtual Telescope Project will also share a live stream of the lunar eclipse above the skyline of Rome.

In fact, the penumbra will start to cover the moon's surface before the partial eclipse proper begins. "It's not even a supermoon this time, just a pretty average full moon".

Unlike solar eclipses, it is perfectly safe to view lunar eclipses with the naked eye and special equipment is not required, the BBC reported.
