Thursday, April 20, 2017, 2:35 PM - The annual Lyrid Meteor Shower will be putting on a show for Earth Day this weekend, and here's your guide to when and where to see it.

The best day to see Lyrid meteors will be extremely early in the morning on Sunday, April 22, NASA meteor expert Bill Cooke told Space.com. Meteor showers occur when the Earth crosses the path of a comet, colliding with a trail of comet crumbs.

The annual Lyrid Meteor Shower will be putting on a show for Earth Day this weekend, and here's your guide to when and where to see it.

Google is revealing ‘the new Google Earth’ next week

  Google is revealing ‘the new Google Earth’ next week Remember Google Earth? Once the coolest and most convenient way to explore the planet on a computer, the app has been largely cannibalized as Maps became ever more powerful. But Google hasn’t forgotten about it, and just sent out invites to the press for an event where it will unveil “the new Google Earth”.

Top off your Earth Day celebrations by getting outside tonight (April 22) and watching a parade of falling stars: The Lyrid meteor shower is still visible tonight, according to NASA. Lyrid Meteor Shower 2018: When, Where & How to See It. Space.

It’s when Earth passes through an unusually thick clump of comet rubble that an elevated number of meteors can be seen . Bottom line: The Lyrid meteor shower offers 10 to 20 meteors per hour at its peak on a moonless night.

On the nights of Friday, April 21 and Saturday, April 22 stargazers may be able to catch a few meteors during the peak of the Lyrid meteor shower.

This meteor shower typically is not one of the strongest of the year, as it only delivers about 15-20 meteors per hour, under ideal conditions (compared to the Quadrantids, Perseids and Geminids, which can produce 100+ an hour!).

It's still well worth the effort to see this shower, though, because the meteors tend to be fairly bright, and some even produce produce fireballs in the night sky.

The radiant of the meteor shower (the point in the sky where the meteors appear to radiate out from) rises at roughly 9 p.m., local time, and can be spotted near Vega, the brightest star in the constellation Lyra.

While some showers spread their meteor crumbs over several days , the Lyrids ' peak activity lasts less than a day . How to See the Best Meteor Showers of 2010: Tools, Tips and 'Save the Dates'. April 22, 2010.

The absolute peak of the shower is expected for 12 UTC on Saturday morning, or around 8 a.m. ET, which means that the pre-dawn hours of Earth Day will likely be the best time to watch for American stargazers. Meteor activity could still be good enough on Saturday night to catch a few then, as well.

Unlike in 2016, when the light of the Full Moon washed out many of the faint meteors from this shower, this year, the phase of the Moon - a waning crescent - is much more favourable for meteor viewing. The crescent Moon will not rise above the horizon until very early Saturday morning, in the hours just before sunrise, so it should not present a problem at all for viewing this meteor shower.

What's going on here?

The Lyrid meteor shower is produced as Earth passes through a stream of debris, left behind in the orbit of a comet known as C/1861 G1 (Thatcher). Comet Thatcher takes a VERY long time to go around the Sun - the last time it went by was in 1861, and it will do so again around the year 2280 - but as it does, it passes fairly close to Earth. It's not close enough to be a danger to us, but close enough that the tiny particles of ice and rock - meteoroids - that it leaves behind in its wake can be swept up by Earth as we go around the Sun.

Google Earth’s massive update adds 3D maps and interactive guided tours of our planet

  Google Earth’s massive update adds 3D maps and interactive guided tours of our planet In its first major update in two years, Google Earth has added a bunch of new features that should make the virtual globe app a lot more fun to play with.&nbsp;Up first is browser support: you no longer need a dedicated desktop or mobile app to view Google Earth as it now loads in Chrome with all its bells and whistles.

The Lyrids , considered the first good meteor shower of the year, will peak on April 22 -- Earth Day -- and April 23. No special equipment will be needed to see the meteors .

While some showers spread their meteor crumbs over several days , the Lyrids ’ peak activity lasts less than a day . Later it was found to be linked to the Lyrid meteor shower . Each year in late April, Earth passes through centuries of dust shed by the comet’s tail.

When that happens, these meteoroids plunge into the atmosphere, travelling at speeds of between tens to hundreds of thousands of kilometres per hour. At that speed, they compress the air molecules in their path together with such force that the air molecules heat up and glow. This glow is what we call a meteor, and the bigger the meteoroid, the greater the force it exerts, and thus the brighter the meteor glows.

In many cases, the heat from the air molecules simply burns away the meteoroid, making for a very short-lived meteor. For some meteoroids, though - the larger ones or the ones made of tougher stuff - they survive the heat and slow down enough where they cannot compress the air enough to make it glow. At this point, they enter what's known as "dark flight" and fall to the ground, to become a meteorite.

Will we be able to see it?

Seeing a meteor shower in action requires a certain amount of forethought.

Getting out from under light polluted urban night skies is a must, as the competing lights from the ground will make it impossible to see any but the brightest meteors or fireballs. The Royal Astronomical Society of Canada has a list of Dark Sky Sites on their website.

Cassini to make last flyby with Titan on Saturday

  Cassini to make last flyby with Titan on Saturday Saturday may be Earth Day here, but for NASA's spacecraft Cassini, it will be Titan Day. Cassini will make its last up-close flyby of Saturn's mysterious, haze-enshrouded moon Titan this weekend. This will be "the mission's final opportunity for up-close observations of the lakes and seas of liquid hydrocarbons that spread across the moon's northern polar region, and the last chance to use its powerful radar to pierce the haze and make detailed images of the surface," NASA said in a statement. Cassini's radar instrument will look for changes in Titan's methane lakes and seas, and attempt for the first (and last) time to study the depth and composition of Titan's smaller lakes. The closest approach to Titan is planned for 2:08 a.m. EDT on Saturday. During that encounter, Cassini will pass as close as 608 miles above Titan's surface at a speed of about 13,000 mph, NASA said. The flyby is also the beginning of the end for Cassini: Once it passes by Titan, its final 22 orbits over the next five months will be between Saturn and its famed rings, ending with a plunge into Saturn on Sept. 15 that will destroy the spacecraft and finish the mission. “I think it is too early to eulogize Cassini on the occasion of its death, as incineration is five months away," said Jonathan Lunine, the director of the Cornell Center for Astrophysics and Planetary Science, who has worked on the Cassini mission since the 1980s.

The shower 's "peak" is when Earth passes through the heart of the dusty trail, and meteors can often be seen for days before and after that peak. [ Lyrid Meteor Shower Seen From Space Station (Video)].

Heres what you need to know about the Lyrids and how to watch the meteor shower in Georgia. 12 hours ago THE Lyrid Meteor Shower is a of the year coincides with Earth Day this year — meaning people all over the world will have the chance to see the 2018 Lyrid meteor shower light up the sky.

Even after escaping to darker skies, anyone watching will need to let their eyes adjust to the dark. So, for roughly 30-45 minutes, avoid looking at any bright light sources, including a smartphone or car headlights. If you must use your phone, switching it to "night mode," so that it displays in the red end of the spectrum of light, rather than the blues, will help. When your eyes are completely adjusted, it will make the meteors much easier to see.

Crucially, though, the skies not only need to be dark, but at least reasonably clear, as well. Here are the forecast sky conditions for Friday night to Saturday morning:

Are there other ways to watch?

Yes! If your skies are clouded over during the best times to watch, try heading over to Slooh.com, to watch their livestream show of the shower. Their broadcast begins at 8 p.m. ET, Friday, April 21.

Also, try watching the meteors on radar. It doesn't show you the glowing streaks in the sky, but its fascinating to watch meteoroids show up as multicoloured peaks in these scrolling, auto-updating 3D radar graphs.

Arkansas events show risk of ambitious execution schedule .
Arkansas' push to put eight men to death in less than two weeks has so far resulted in just one lethal injection, and legal experts say that shows the risks of pursuing the nation's most ambitious execution schedule since the death penalty was restored in 1976.Ledell Lee was executed minutes before his death warrant was set to expire late Thursday. It was the first time since 2005 that Arkansas had put an inmate to death.Three other planned executions were canceled this week because of court decisions. Another inmate scheduled for execution next week has received a stay. And three remaining lethal injections face similar hurdles.
