What tools can be used to see galaxies?
If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to use
a telescope with an aperture of 8 inches or more
. Bode’s Galaxy (M81) glows brightly enough to show up through binoculars, but the larger the telescope you can point at it, the better.
Which instrument is most commonly used to study the universe?
The key instrument of nearly all modern observational astronomy is
the telescope
.
Which type of galaxy is largest?
The universe’s largest-known galaxies—
giant elliptical galaxies
—can contain up to a trillion stars and span two million light-years across. Elliptical galaxies may also be small, in which case they are called dwarf elliptical galaxies.
What kinds of astronomy can be done from the ground?
Ground-based telescopes
avoid the risk of putting telescopes in the orbit through rockets. The ground-based telescopes are mostly used to study the stars, which emit visible light or radio waves that are not blocked either by the ozone layer or by the water and carbon dioxide in the upper atmosphere of the Earth.
Is Hubble still working and in space?
NASA anticipates that Hubble will last for many more years and will continue making groundbreaking observations, working in tandem with other space observatories including the James Webb Space Telescope to further our knowledge of the cosmos. Launched in 1990,
Hubble has been observing the universe for over 31 years
.
Who built the first telescope?
While there is evidence that the principals of telescopes were known in the late 16th century, the first telescopes were created in the Netherlands in 1608.
Spectacle makers Hans Lippershey & Zacharias Janssen and Jacob Metius
independently created telescopes.
What do astronomers use to study space?
Astronomers study planets, stars, galaxies, and other celestial bodies. They use ground-based equipment, such as
radio and optical telescopes
, and space-based equipment, such as the Hubble Space Telescope.
What do all stars have in common?
Basically, stars are big exploding balls of gas, mostly
hydrogen and helium
. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb.
What tools do cosmologists use?
Observational cosmology is the study of the structure, the evolution and the origin of the universe through observation, using instruments such as
telescopes and cosmic ray detectors
.
What stars are the coolest?
You can tell the temperature of the star.
Red stars
are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow.
What model did Aristotle and Ptolemy propose?
The geocentric model
was the predominant description of the cosmos in many ancient civilizations, such as those of Aristotle in Classical Greece and Ptolemy in Roman Egypt.
