Meteor showers have been observed for hundreds of years, and they continue to provide scientists with valuable data even today.
This is significant because the asteroids and comets that produce meteors contain evidence of the solar system’s history that can shed light on how our planet and others like it formed.
By learning more about the conditions in space, space agencies and companies can ensure the safety of their orbiting spacecraft by studying meteor showers.
Satellites are vulnerable to damage or complete shutdown if rocks or dust traveling at high speeds collide with them.
What’s going on: Scientists all over the world will be keeping a close eye out for meteors in November and December, the peak months for annual meteor showers.
As we speak, the Taurid meteor shower is in full swing, and the Leonid meteor shower is gearing up for its peak around mid-month.
“Most of the fireballs created by Taurids are smaller than a baseball or a pebble, not because they are particularly fast.
Although the Leonids travel at high speeds, they are only dust in the sky “Axios quotes Bill Cooke, a NASA astronomer.
Meteors as bright as, or brighter than, Venus in the night sky are known as fireballs.
Midway through December, stargazers can expect the best of the year’s meteor showers: the Geminids.
This is how it operates: Scientists all over the world are constantly scanning the sky for meteors using powerful radar systems.
While some radar systems are on all the time, the more sensitive and expensive instruments that can detect even the tiniest meteors can only be used for a limited time.
An astronomer from the University of Maryland, College Park, named Quanzhi Ye, tells Axios that citizen scientists using their own backyard cameras also contribute significant data to the field. Data on meteor showers and their timing are two examples of the kinds of information that can be contributed.
Meteor observations, Ye argued, need not be conducted in a high-tech facility costing a million dollars. When money is tight, “sometimes you can just use your eye” or “sometimes you can spend like a few hundred dollars and build your own cameras.”
As a whole, meteor showers occur when Earth travels through comet or asteroid debris trails.
The Earth passes through a region of these debris trails at roughly the same time every year. Other meteor showers occur at random intervals and are caused by whatever comets or asteroids have recently passed through Earth’s orbit.
Without ever physically visiting the asteroid or comet that sheds its dust and rock, scientists can learn more about it by studying the meteor’s trail, which can reveal information about the object’s size, speed, brightness, and composition.

Miriam Kramer, host of the “How it Happened” podcast and author of the Axios Space newsletter, authored the Axios article.
The author mentioned that this month would also see the Leonid meteor shower and that the Taurid meteor shower was currently occurring.
NASA astronomer Bill Cooke claims that the abundance of fireballs caused by the Taurid meteors can be attributed to their small sizes, which are on par with pebbles or baseballs.
Cooke elaborated by saying that despite their minuscule size, Leonid meteors traveled at incredible velocities.
Which Characteristics Distinguish These Space Rocks From One Another?
They’re all associated with the meteor-like bursts of light known as shooting stars. However, we give the same thing a variety of names depending on where we are.

Sizes of meteoroids in space range from dust particles to minor asteroids. Imagine them as “rocks from outer space.”
Fireballs or “shooting stars” are meteors, and they are caused by meteoroids crashing into Earth’s (or another planet’s, like Mars’) atmosphere at high speed and burning up.
The term “meteorite” is used to describe a meteoroid that has made it through Earth’s atmosphere and down to the ground.
What Is A Meteor Shower?
Every day, the Earth receives an estimated 44,000 kilograms (44 tons) of meteoritic material, according to scientists. In the Earth’s atmosphere, nearly all of the material is vaporized, leaving behind a brilliant trail known as a “shooting star.
” Most nights will have at least a handful of meteors visible per hour. Meteor showers occur when the number of meteors in the sky suddenly increases.
As the Earth travels through the dusty debris left by a comet, meteor showers can occur on a yearly or semiannual basis.
Many meteor showers are named after stars or constellations that are relatively close to the area of the sky where the meteors are seen to appear to rain down from the heavens.
The Perseids are arguably the most well-known, with their peak occurring every August. Every meteor seen during the Perseid meteor shower is a fragment of the comet Swift-Tuttle, which orbits the Sun once every 135 years.
Photographing a meteor shower can be a test of patience, as meteors streak across the sky quickly and without warning, but with these guidelines and a little luck, you just might get a great shot.
Although these guidelines are written with a DSLR or mirrorless camera in mind, those who have a point-and-shoot camera with manual controls may find them useful as well.
