The Eta Aquarids, the first half of Halley’s Comet’s two rounds of meteor showers, peak May 4-6, 2021. The two meteor showers are debris from Comet Halley as Earth passes through the comet’s path around the Sun.
Seen in both hemispheres, the Southern Hemisphere arguably offers a better view now when its radiant, the Aquarius constellation, is overhead and Northern is better for its second round, the Orionids, in October. But both meteor showers are popular with sky watchers.
After acclimating your sight to the night, look in the southern sky for Eta Aquarii, the constellation’s brightest star. Depending on the weather, you may be treated to more than 30 meteorites per hour.
The moon, now in its waning crescent phase should not be a factor, particularly if watching for the meteorites early on May 6 before dawn.
Forget about turning off the light that may be keeping you up on April 26-27. It’s streaming in through the windows from upstairs, outside. However, the source will have seemed larger earlier in the evening.
What’s shining through the windows if the sky is clear, is not merely a full moon. The orb outside is a Supermoon. It really isn’t larger. It just plays tricks on the eyes and perspective as it appears huge when first appearing at the horizon and in early evening.
The April full moon, also known as the “Pink Moon” is a Supermoon because it will be closer to Earth than most other full moons. The exception being the full moon in May 26, called the “Flower Moon” that will be even closer.
Some astronomy sites only designate the April and May full moons as Supermoons. Other sites include June 24’s which is also close. Still other sites include the March full moon which was fairly close.
For times to watch or photograph the moon check. EarthSky. The site also has the April, May June, 2021 Supermoons’ distances from the moon to Earth with April 27 at 222,212 miles (357,615 km), May 26 at 222,089 miles (357,462km) and June 24 at 224,662 miles (361,558 km).
If interested in how this all happens, you should know about the lunar perigee. It’s when the moon’s orbit brings it to its closest point to Earth. The opposite is apogee.
Of course, the third factor is where the earth is in relation to the moon and the sun to be a full moon. So, the April Supermoon actually happens about 12 hours short of it lunar perigee and May’s Supermoon falls about nine hours after perigee. The reason some sites refer just to April and May’s full moons as Supermoons is because less than 24 hours occur between the perigee and full moon phase.
Next, don’t be surprised if bothered with sinus trouble and have a full-moon sized headache. Because the pull of the full moon, particuclarly the Supermoon, does influence the tides, lore has it that their affect on humans and animals can also be felt.
Assuming the weather cooperates, early risers should have no trouble spotting a fireball zooming across the sky shortly before dawn in the next few days. The Lyrids meteor shower is happening now.
They seem to be shooting out (radiant) from the Lyric constellation just northwest of its bright Vega star. They are debris from the comet Thatcher (C/1861 G1), first noted more than 2,500 years ago.
The best days to look for them are April 21-22 when the Lyrids are expected to peak at about 18 meteors an hour. Pre dawn is the best time to watch because the moon is waxing gibbous so its illumination won’t be a factor after it sets.
For the time to watch in your zone visit Time and Date. For more information on where to look visit Space which has a map to help find the radiant. For more basic meteor and Lyrid information visit NASA Lyrids.
Escape from our earthly pandemic April 12, 2021 via NASA.
Tune in to NASA Live or NASA online early, actually very early, Monday morning when, if all goes as planned, Ingenuity, the Mars Helicopter, will be seen moving and hovering beginning at 3:30 a.m. EDT.
A post flight briefing is planned for 11 a.m. EDT, April 12.
Ingenuity’s inaugural flight will livestream to (hopefully) demonstrate the first powered flight on another planet.
Don’t expect the kind of helicopter tour often touted for visiting Hawaii or the Grand Canyon. Ingenuity will be starting out slow and low in Mars’ freezing temperatures and thin air. If all goes well, it will move just a few feet up and hover a few seconds before landing.
‘That will be a major milestone: the very first powered flight in the extremely thin atmosphere of Mars, ” said a NASA statement.
Ingenuity demonstrations are expected to continue with greater altitude and distance for approximately 31 Martian days (sols). Then, Perseverance will continue its exploratory mission.
The helicopter was attached to the Perseverance rover that landed at the Jezero Crater on Mars, Feb. 18, 2021. Perseverance released Ingenuity upon reaching what was considered to be a good “helipad.”
If the light of the moon was keeping you up last night it’s because the first full moon of spring is March 28 but looks full March 27 and March 29.
And because this spring (Northern Hemisphere) full moon is closer to earth than the ones in January and February it appears brighter and is considered by some sky watchers as a “Supermoon.”
Actually, its perigee (closest part of its orbit) is March 30 so it still will continue to appear very bright and mostly full.
Don’t worry if your area is cloudy. The full moons in April, May and June will be even closer and will look like Supermoons.
Called the Worm Moon, Crow Moon or Sap Moon by some native American tribes, this full moon also sets Easter, which, in 2021, is April 4. See Tonight | EarthSky
Fun Fact:Do you know what syzygy means? It’s when three bodies, such as the Sun, Earth, and the Moon, are in alignment. See Time and Date for the term and alignment.
Time and Date also does an excellent job of explaining how long the moon really is fully illuminated and why due to the earth’s tilt it may not appear at total illumination, noting that the degree of illumination somewhat blends what appears to be a Full Moon and the last stage of a Waxing Gibbous Moon or the beginning of a Waning Gibbous Moon.
On NASA’s site a sidebar tells that the term “supermoon” was “coined by the astrologer Richard Nolle in 1979 and refers to either a new or full Moon that occurs when the Moon is within 90% of perigee, its closest approach to Earth.’
The site also connects the first spring moon’s names from native Americans and different religions. It notes that this weekend’s Full moon is also called the Pesach moon on the Jewish calendar, Paschal moon for Western Christianity and Medin in SRI Lanka.
For more word definitions and moon phases visit Space.
According to several astronomy sources it was northeastern native Americans who dubbed February’s full moon the Snow Moon.
Given the amount of snow that covered much of the United States in February, the moon is well named. It’s also called the Storm Moon and Hunger Moon.
That orb will be lighting up the landscape Thursday, Friday and Saturday but best time to view will be Friday night from when it appears above the horizon in the east as the sun sets to midnight when it is overhead.
Some studies mentioned by EarthSky have been done on the relationship of full moons to sleeplessness from the light point of view. Hopefully, scientists will also look at the tidal pull of full moons on sinuses.
NASA countdown to Space X’s Crew Dragon is happening now, Nov. 13, 2020
For the press conference with administrator Jim Bridenstine and officials from NASA and Japan Aerospace Exploration Agency go to NASA YouTube watch.
For the countdown on Nov. 14 Go to NASA You Tube FLA. Watch the first (this mission has many firsts) crew rotation flight by a U. S. Commercial spacecraft to the International Space Station.
This is the first four person-crew in a capsule and commercial flight. Crew members are NASA astronauts Michael Hopkin, the Crew Dragon commander, pilot Victor Glover and mission specialist Shannon Walker plus JAXA mission specialist astronaut Soichi Noguchi.
Liftoff is 7:49 p.m. EST from NASA’s Kennedy Space Center’s Launch Complex 39 A in Florida.
The mission will be six months. Other firsts include Walker as the first woman on a commercial orbital mission, Noguchi8 as the first international partner astronaught to fly on three types of orbital spacecraft.
Check the weather predictions in your area for Aug. 11-13. That is when the Perseids are supposed to be peaking with bright meteors shooting across the sky at 50 to 100 an hour.
Best time say the experts, is in the northern hemisphere right before dawn, so also check the sunrise times for your area.
Because these meteors are bright, plentiful and have long tails, the largish waning crescent moon might not be much of a hindrance the night of Aug. 11. By Aug 13 the moon will be thinner though there may be fewer meteors.to spot.
So where do they come from?
The Perseids are debris from the 109P/Swift-Tuttle comet. They are called Perseids because they look like they emanate (their radiant) from the Perseus constellation as the Earth moves through their trail each summer.
The comet’s name comes from Lewis Swift and Horace Tuttle who discovered it in 1862.
