Which galaxy is older spiral or elliptical?
Astronomers have identified more spiral galaxies than ellipticals, but that’s simply because the spirals are easier to spot. While spiral galaxies are bright, elliptical galaxies are dim. The existing stars inside an elliptical galaxy tend to be older, giving off more red light than younger stars.
What type of galaxy is most common elliptical irregular lens spiral?
spiral galaxies
What are the four types of galaxy classifications?
Edwin Hubble invented a classification of galaxies and grouped them into four classes: spirals, barred spirals, ellipticals and irregulars. He classified spiral and barred spiral galaxies further according to the size of their central bulge and the texture of their arms.
What are the two types of elliptical galaxies?
It is sometimes said that there are two physical types of ellipticals: the giant ellipticals with slightly “boxy”-shaped isophotes, whose shapes result from random motion which is greater in some directions than in others (anisotropic random motion); and the “disky” normal and dwarf ellipticals, which contain disks.
What is the major difference between an elliptical galaxy and a spiral galaxy?
The major difference between spiral and elliptical galaxies is that elliptical galaxies lack a significant disk component, although both types have the halo component.
What is the oldest type of galaxy?
GN-z11
What is the rarest type of galaxy?
elliptical double-ringed galaxy
Is there anything bigger than the universe?
Cosmos At Least 250x Bigger Than Visible Universe, Say Cosmologists. The universe is much bigger than it looks, according to a study of the latest observations.
What is the most weakest thing in the world?
According to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure. When it comes to metals, scientists try to measure hardness in absolute terms.
What is the most powerful engine ever made?
Its largest 14-cylinder version is 13.5 metres (44 ft) high, 26.59 m (87 ft) long, weighs over 2,300 tons, and produces 80,080 kW (107,390 hp). The engine is the largest reciprocating engine in the world….Wärtsilä-Sulzer RTA96-C.

Does higher compression increase torque?
Increase in compression ratio induces greater turning effect on the cylinder crank. That means that the engine is giving more push on the piston, and more torque is generated.
Is there a straight 8 engine?
The straight-eight engine or inline-eight engine (often abbreviated as I8 or L8) is an eight-cylinder internal combustion engine with all eight cylinders mounted in a straight line along the crankcase. The type has been produced in side-valve, IOE, overhead-valve, sleeve-valve, and overhead-cam configurations.
Is there a 7 cylinder engine?
A straight-seven engine or inline-seven engine is a straight engine with seven cylinders. Wärtsilä also produces regular trunk engines in this configuration. It is more common in marine applications because marine engines are usually based on a modular design, with individual heads per cylinder.
What is the biggest inline engine?
The smallest automotive straight-four engine was used in the 1963-1967 Honda T360 kei truck and has a displacement of 356 cc (21.7 cu in), while the largest mass-produced straight-four car engine is the 1999-2019 Mitsubishi 4M41 diesel engine which was used in the Mitsubishi Pajero and has a displacement of 3.2 L (195 …
Do V4 engines exist?
A V4 engine is a four-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. V4 engines are much less common than inline-four engines. However, V4 engines have been used at times in automobiles, motorcycles, and other applications.
What car has the best engine?

What cars use a V4 engine?
Here’s a short list of some of the most important cars to use the V4 engine.
- Saab Sonett V4. Debuted with a 2-stroke inline 3, the Saab Sonett II eventually received a V4 from Ford in 1967.
- J. Walter Christie V4 Racer.
- Ford Transit Mark 1.
- M422 “Mighty Mite”
- Lancia Fulvia.
- ZAZ-965.
Is there a V2 engine?
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The V-twin design dates back to the late 1880s.
What is the biggest V-twin engine?
No, this bike is all about the engine. And what an engine it is. The fuel-injected 45-degree V-twin displaces 6,728 cubic centimeters. That’s three times larger than the Triumph Rocket III Classic — the largest production motorcycle in the world — and the biggest thing between two wheels short of the V8 Boss Hoss.
What does V-twin engine mean?
A V-twin engine is a two-cylinder piston engine typically found in motorcycles. Each cylinder shares a common crankshaft and is arranged in a way that make the engine look like a “V”. As an example, most Harley Davidson V-twin engines have a 45-degree angle to the V-shape to allow for optimal balance.
Is there a V5 engine?
A V5 engine is a five-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. V5 engine designs are very uncommon, with the only production version of one being the 1997-2006 Volkswagen Group VR5 (Valvetrain 5) engine.
