Who discovered Tadpole Galaxy?

Such compact galaxy groups were identified in 1982 by astronomer Paul Hickson, who published a catalog of 100 such groups.

What is inside the Tadpole Galaxy?

The Tadpole is a distorted spiral galaxy. Its long streamer of debris was caused by the intrusion of a small galaxy tightly packed with stars. The intruder galaxy, the bright clump to the upper right of the larger galaxy’s core, now lies about 300,000 light-years beyond the Tadpole.

Is Canis Major a galaxy?

A small, irregular galaxy with a mass of about a billion solar masses, the Canis Major dwarf galaxy is one of our closest neighbours, lying approximately 25,000 light years from the Sun and 42,000 light years from the centre of the Milky Way.

What planets are in Andromeda?

Does the Andromeda Galaxy have planets? There is currently only one very strong candidate planet in the Andromeda Galaxy, temporarily named PA-99-N2. It was detected because of a microlensing event in 1999.

Is Comet a galaxy?

The Comet Galaxy, a spiral galaxy located 3.2 billion light-years from Earth, in the galaxy cluster Abell 2667, was found with the Hubble Space Telescope. This galaxy has slightly more mass than our Milky Way.
…

How did the Tadpole Galaxy get its name?

The Tadpole galaxy is a disrupted barred spiral galaxy in the constellation of Draco. The Tadpole galaxy is named the Tadpole galaxy because it’s shape and star formation resembles that is a Tadpole. The merger of the head and tail of the galaxy is believed to have happened around 100 million years ago. …

Is the Tadpole Galaxy a spiral galaxy?

Dubbed the “Tadpole,” this spiral galaxy is unlike the textbook images of stately galaxies. Its distorted shape was caused by a small interloper, a very blue, compact galaxy visible in the upper left corner of the more massive Tadpole. The Tadpole resides about 420 million light-years away in the constellation Draco.

Is Comet a planet?

They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. … Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.

What happens if a comet hits the Sun?

What will happen? Nothing will happen. The mass and the heat of the Sun are of such magnitude that even the biggest object in the solar system, Jupiter, hitting the Sun would cause just a momentary hiccup, and comets are actually tiny objects in the scale of the solar system.

Why do comets have tails?

Comets leave long beautiful tails when they come close to the sun. … But when it approaches the sun, the heat evaporates the comet’s gases, causing it to emit dust and microparticles (electrons and ions). These materials form a tail whose flow is affected by the sun’s radiation pressure.

Does dust have a long tail?

properties of comets

The dust tail forms from those dust particles and is blown back by solar radiation pressure to form a long curving tail that is typically white or yellow in colour. … …from the Sun, and the dust (Type II) tails coming from solar radiation pressure on the fine dust particles emitted from the comet.

Is Comet a shooting star?

Meteors (or shooting stars) are very different from comets, although the two can be related. A Comet is a ball of ice and dirt, orbiting the Sun (usually millions of miles from Earth). … A Meteor on the other hand, is a grain of dust or rock (see where this is going) that burns up as it enters the Earth’s atmosphere.

What is Sun’s orbit?

Orbit and Rotation

The Sun orbits the center of the Milky Way, bringing with it the planets, asteroids, comets, and other objects in our solar system. Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour).

Why do comets have 2 tails?

Comets have two tails because escaping gas and dust are influenced by the Sun in slightly different ways, and the tails point in slightly different directions. Gases escaping from the comet are ionized by the ultraviolet photons from the Sun. … These gases form the plasma tail.

Why do comets tails face away from the Sun?

Comet tails will always point away from the sun because of the radiation pressure of sunlight. The force from sunlight on the small dust particles pushing them away from the sun is greater than the force of gravity acting in the direction toward the sun.

What is ion tail?

The blue ion tail contains charged particles swept from the coma by the solar wind. … Alternatively known as the ‘ion tail’ or ‘plasma tail’, the gas tail of a comet generally starts to form somewhere around the orbit of Mars.

How big is the biggest comet?

At 100 km across, comet BB is the largest comet ever discovered by far, and it is farther from the sun than the planet Uranus. Most comets are around 1 km or so and much closer to the sun when they are discovered.

Does the Sun leave a trail?

No, the sun does not leave a trail. But the solar system does. For something to leave a trail, there has to be some kind of resistance or friction. When an airliner leaves a trail in the sky, it because it is moving through the atmosphere, which isn’t moving with the plane (if it did the plane wouldn’t fly).

Can comets crash into each other?

Given the large expanse of empty space in the solar system, and the relatively small size of the comets, a collision between two comets would be pretty rare. Such collisions are so rare that, to my knowledge, there has never been a record observation of comets colliding with each other! … A sideways collision.

Is there a comet that will hit Earth?

On average, an asteroid the size of Apophis (370 metres) is expected to impact Earth once in about 80,000 years.

Is a comet coming in 2022?

Bottom line: A new comet named C/2021 O3 (PanSTARRS) will visit the sun and be closest to Earth in the spring of 2022. It might become visible to the unaided eye.

What is the rarest comet?

Halley’s Comet, the Rare Visitor

Visible from a variety of locations on Earth with the naked eye, it has a length of 9 miles and a width of 5 miles. Comprised mostly of icy particles, Halley’s Comet paid us a visit in 1986 and will not return until the year 2061.

How big is the asteroid that killed the dinosaurs?

The asteroid was about 7.5 miles (12 kilometers) in diameter and was traveling about 27,000 mph (43,000 km/h) when it created a 124-mile-wide (200 km) scar on the planet’s surface, said Sean Gulick, a research professor at the University of Texas Institute for Geophysics, who led the study.
