Causal observers and avid stargazers have a lot to look forward to in the new year, including one event that won't happen again for nearly another two decades.
Here are the top astronomy events to mark on your calendar in 2020:
1. Series of supermoons
When: February - May
When: February - May
Several times a year, the full moon appears slightly bigger than normal in the night sky, an event that in recent years has been come to be known a supermoon.

In 2020, the night sky will feature four supermoons in a row, starting in February and glowing big and bright once each month through May. Although supermoons have gained much attention in recent years, to the common observer, they will look just like many other full moons throughout the year.
2. Moon passes in front of Mars
When: Feb. 18
When: Feb. 18
Early risers stepping outside before dawn on Feb. 18 will get to see a rare event similar to an eclipse as the Moon passes directly between the Earth and Mars, known as an occultation.

Such events happen very frequently but in most cases the star being occulted may be very faint. However, when bright stars or planets such as Venus are occulted by the moon, the event can be seen with the naked eyes.(AP Photo/ Nader Daoud)
Most areas of North America will be able to see Mars disappear behind the moon just before sunrise in the southeastern sky, reappearing on the other side a little more than two hours later. The exact time that this will be visible varies from location to location.
3. Meteor shower drought comes to an end
When: April 22-23, May 6-7
When: April 22-23, May 6-7
The long and cold winter nights seldom feature onslaughts of shooting stars, but as the seasons change, so too will the night sky.
After the Quadrantids peak in early January, stargazers will need to wait more than three months for the next opportunity to see a meteor shower, with the Lyrids peaking on the night of April 22 into the early morning hours of April 23.

Folks won’t need to wait nearly as long for another meteor shower to put on a dazzling display in the night sky, with the Eta Aquarids peaking just two weeks later. This is one of the best meteor showers of the year for the Southern Hemisphere that is known to produce up to 60 shooting stars per hour.
4. Lunar eclipse on the Fourth of July
When: July 4-5
When: July 4-5
Four penumbral lunar eclipses will be visible across the world in 2020, a type of eclipse where the moon passes through just the outer part of the Earth’s shadow. Two of these lunar eclipses will be visible from North America, but they may be difficult to see unless you look closely.

The first of the two North America lunar eclipses will take place after the sun sets on July Fourth. The second will fall shortly after Thanksgiving on the night of Nov. 29 into the early hours of Nov. 30.
5. Jupiter, Saturn to take the spotlight in the summer sky
When: Mid-July
When: Mid-July
The two biggest planets in our solar system will be the main feature in the summer sky as Jupiter and Saturn shine side by side all season long.
The middle of July will be the best time of the summer to view the planets, with or without a telescope, as they will both be reaching opposition. This is the point in their orbits where they will be closest to the Earth, making them appear brighter than any other point in the year. Jupiter will reach opposition first on July 14 followed by Saturn on July 20.
6. Perseid meteor shower
When: Aug. 12-13
When: Aug. 12-13
The Perseid meteor shower is regularly one of the top three meteor showers of the year, and the 2020 showing in mid-August will be much better than the one from 2019.

Unlike in 2019 when the nearly full moon filled the sky with light, the moon will be in the sky for only the last part of the night, allowing stargazers to see as many as 100 meteors per hour.
“Perseids are not only numerous; they are beautiful. Most of the meteors leave a glittering trail as they pass,” AccuWeather Astronomy Blogger Dave Samuhel said. “They are multi-colored and many are bright!”
7. Blue moon to glow in Halloween sky
When: Oct. 31
When: Oct. 31
Young masqueraders heading out to collect candy in their neighborhoods on Halloween will do so under the light of a blue moon that will rise on the final night of the month.
Blue moons are uncommon, rising once every two or three years, but a blue moon on Halloween is very rare. After the blue moon on Oct. 31, 2020, trick-or-treaters will need to wait until 2039 to see the next blue moon on Halloween.
8. Moonless sky in store for peak of the Geminids
When: Dec. 13-14
When: Dec. 13-14
Arguably the best meteor shower of the year will reach its pinnacle on the night of Dec. 13 into the early morning hours of Dec. 14.
This year, the Geminids will peak on a moonless night, allowing the shower to reach its full potential. Stargazers braving the chilly December night may be able to see as many as 150 meteors per hour in dark areas away from city lights.
9. Total solar eclipse to darken sky over South America
When: Dec. 14
When: Dec. 14
The only total solar eclipse of the year will cause day to turn to night on Dec. 14, just hours after the peak of the Geminids.

Most of the eclipse will transpire over the unpopulated waters of the southern Atlantic Ocean and the southeastern Pacific Ocean, but the path of totality will traverse across a swath of South America. The locations able to witness the total solar eclipse will be very close to the areas that saw the only total solar eclipse of 2019.
10. Super conjunction of Jupiter and Saturn
When: Dec. 21
When: Dec. 21
The final astronomy event of the year will be one of the most intriguing as Jupiter and Saturn make an extremely close encounter following the first sunset of winter.
When two planets appear close in the sky, astronomers call it a conjunction. However, this meeting of Jupiter and Saturn on the first night of winter will be incredibly close, the closest they have been since 1623, according to the Royal Astronomical Society of Canada. This extraordinarily close encounter is sometimes referred to as a 'super conjunction.'

People looking to the southwestern sky may mistake the two planets for one really bright star while those with high-powered telescopes will be able to see the planets in the same field of view.
Jupiter and Saturn will remain close in the night sky following the super conjunction on Dec. 21, but they will slowly drift apart through the rest of the year.
