The blue moon is the second full moon in a calendar month. Now, people know that to be rare since the saying goes, "once in a blue moon." Those occur about once every two-and-a-half years. The black moon is when we have a second new moon in a calendar month.
Saturn, top, and Jupiter, below, are seen after sunset from Shenandoah National Park, Sunday, Dec. 13, 2020, in Luray, Virginia. The two planets are drawing closer to each other in the sky as they head towards a “great conjunction” on December 21, where the two giant planets will appear a tenth of a degree apart.
When we talk about 2020 as the worst year ever we mean many entangled things: A pandemic. The death and economic destruction caused by the pandemic. The governmental mismanagement of the pandemic. The ways the pandemic has exposed the failures of our social system.

This is caused by atmospheric lensing. You see as light from the sun enters our atmosphere it becomes diffused. While at sunset the sun looks larger, it is only because you are seeing the light being spread out over a larger perceived area. You look directly up, and the sun appears smaller, much smaller.
It's also the planet that is easiest to find in the night sky – or more correctly, the dusk or dawn sky. Venus is never farther than 48 degrees from the sun and is visible for a little less than three hours after sunset or before dawn.
Rare Super Blue Blood Moon Eclipse Thrills Millions Around the World. The second full moon of January passed through Earth's shadow in a Super Blue Blood Moon eclipse today (Jan. 31), a rare lunar sight visible to millions of observers around the world.
In any given location on Earth, a total eclipse happens only once every hundred years or so, though for selected locations they can occur as little as a few years apart. An example is the August 21, 2017 and April 8, 2024 eclipses, which will be viewed at the same spot near Carbondale, Illinois.

Conjunction: Planetary AlignmentA planetary alignment is the common term for the planets being lined up at one time. A combination of at least two bodies lined up in the same area of the sky, as seen from earth, is a conjunction.
Blood Moons happen about twice a year. While this may be exciting to most, you may not be able to see the Blood Moon. Depending on the angle and position of your location, the Moon may not appear as red, or you may not be able to see it.
Blue moons are relatively rare as well, occurring on average just once every 2.5 years or so. We last saw one in March 2018.
Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates outside Earth's atmosphere.
Since the 20th century there have been two main types of astronomy, observational and theoretical astronomy. Observational astronomy uses telescopes and cameras to observe or look at stars, galaxies and other astronomical objects.
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth. In astronomy, the Universe is our laboratory!
"You take the light from a star, planet or galaxy and pass it through a spectroscope, which is a bit like a prism letting you split the light into its component colours. "It lets you see the chemicals being absorbed or emitted by the light source. From this you can work out all sorts of things," says Watson.
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.
How to Become an Astronomer
- Take astronomy-related classes in high school.
- Earn an undergraduate degree in a scientific field.
- Meet other aspiring astronomers.
- Earn a doctorate in astronomy.
- Get a postdoctoral research position or fellowship.
- Apply for astronomer positions.
Astronomy is the study of everything in the universe beyond Earth's atmosphere. That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars . Early observers looking at the night sky noticed patterns in the stars .
Answer. “Once in a blue moon” is a common expression that has been used for a long time, and which means 'not very often,' or 'very rarely. ' It often refers to an extra full moon; however, it has been used to describe the way the moon actually looked, when for different reasons it had turned a blueish color.
Normally blue moons come only about every two or three years. In 2018 unusually, we had two blue moons in one year and only two months apart – and one was a lunar eclipse! The next time we will get two blue moons in a year will be 2037.
In their outward order from the sun, the five bright planets are Mercury, Venus, Mars, Jupiter and Saturn. These planets actually do appear bright in our sky. They are typically as bright as – or brighter than – the brightest stars.
1 : of, relating to, or suggesting heaven or divinity celestial beings. 2 : of or relating to the sky or visible heavens the sun, moon, and stars are celestial bodies.
30, 2020, North and South America will see the last penumbral eclipse of the year, including Asia, Australia and the Pacific region. A Blood Moon spears only twice in three years. But, the number of total lunar eclipses witnessed in a year can vary.
Going by our broad definition of the term (and ignoring new moons), there will be two supermoons in 2021.
During a total lunar eclipse, Earth lines up between the Moon and the Sun. This hides the Moon from the sunlight. The air molecules from Earth's atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon's surface with a red glow, making the Moon appear red in the night sky.
According to this Almanac, as the full Moon in June and the last full Moon of spring, the Algonquin tribes called this the Strawberry Moon. The name comes from the relatively short season for harvesting strawberries in the north-eastern United States.
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky.
