What kind of galaxy is the LMC?

satellite dwarf galaxy
The Large Magellanic Cloud (LMC) is a satellite dwarf galaxy of the Milky Way that is among the closest galaxies to Earth. At about 163,000 light-years from Earth, the dwarf galaxy looks like a faint cloud in Southern Hemisphere skies.

How many stars does the LMC have?

30 billionLarge Magellanic Cloud / Stars
As some of the closest galaxies to our home galaxy, they stand out as big, misty blobs of light under dark skies. Scientists estimate the Small Magellanic Cloud contains around 3 billion stars, while the Large Magellanic Cloud houses some 30 billion stars.

What are the Magellanic Clouds what happened in the LMC in 1987?

In 1987, a supernova detonated in the Large Magellanic Cloud – the brightest supernova seen in 300 years. For a brief time, the supernova was visible with the unaided eye. The supernova remnant is still being studied as it continues to evolve and expand.

Was the Large Magellanic Cloud a spiral galaxy?

The LMC is classified as a Magellanic spiral. It contains a stellar bar that is geometrically off center, suggesting that it was a barred dwarf spiral galaxy before its spiral arms were disrupted, likely by tidal interactions from the Small Magellanic Cloud (SMC) and the Milky Way’s gravity.

Can you see LMC with naked eye?

The LMC is also one of very few galaxies that are visible to the unaided eye. The galaxy appears as a faint cloud more than 20 times the width of the full Moon.

Why was Supernova 1987A special?

It was the first supernova that modern astronomers were able to study in great detail, and its observations have provided much insight into core-collapse supernovae.

What was the last star to explode?

Witnessing a dying star’s explosive end By the following fall, the star had gone boom. Luckily, the researchers were able to obtain a spectrum of the explosion, now called supernova 2020tlf, aka SN 2020tlf. The results showed evidence of dense circumstellar material around the star.

What is going on in the galaxy Arp 252?

8) Arp 252 — The interaction between these two spiral galaxies has distorted their spiral arms, stretching them out into long tails. These long tails are characteristic of galaxy collisions and interactions. Arp 252 gets its name from a catalog of peculiar and interacting galaxies, put together by astronomer Halton C.

What type of galaxy is Leo 1?

dwarf spheroidal galaxy
Leo I is a dwarf spheroidal galaxy located about 820,000 light-years away in the constellation of Leo. Also known as DDO 74, LEDA 29488 and UGC 5470, the galaxy is a member of the Local Group. Leo I is thought to be one of the most distant satellites of our Milky Way Galaxy.

How far is Andromeda from our galaxy?

2.537 million light yearsAndromeda Galaxy / Distance to Earth

At approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way’s largest galactic neighbor.

Does LMC have supermassive black hole?

The atypical brightness of the LMC is just one of the several features that make our galaxy stand out. For its bulge mass, the MW has a supermassive black hole whose mass is nearly an order of magnitude too small (Savorgnan et al. 2016).

What did 1987A look like?

SN 1987A was a type II supernova in the Large Magellanic Cloud, a dwarf satellite galaxy of the Milky Way….SN 1987A.

Supernova 1987A is the bright star at the centre of the image, near the Tarantula nebula.

Will the supernova in 2022 happen?

While scientists are confident a supernova will occur in 2022, whether it occurs in our galaxy is a different matter. In any given year, it is an unlikely prospect. On the other hand, one day it may just happen in our galactic neighbourhood. If it does, astronomers say they will be ready.

How big is the Needle Galaxy?

The Needle Galaxy is about 40 million lightyears away and is about one third larger than our home galaxy the Milky Way. Below is a selection of pictures of the Needle Galaxy captured by BBC Sky at Night Magazine readers and astrophotographers from around the world.

What kind of galaxy is M59?

elliptical galaxies
M59 is one of the largest elliptical galaxies in the Virgo galaxy cluster. However, it is still considerably less massive, and at a magnitude of 9.8, less luminous than other elliptical galaxies in the cluster.

Will humans survive Andromeda collision?

Luckily, experts think that Earth will survive, but it won’t be entirely unaffected. The collision will unfold right in front of us, changing the night sky to look like nothing any human has seen before.
