3. The Hubble Space Telescope is a robotic telescope
located at the outer edges of the atmosphere, in
circular orbit around the Earth at 593 km above sea
level, with an orbital period between 96 and 97 min.
at a speed of 28,000 km / h. Called Hubble in honor
of Edwin Hubble, was launched on April 24, 1990 as
a joint project of NASA and ESA inaugurating the
Great Observatories program. Weighs about 11,000
kilos, is cylindrical and has a length of 13.2 m and a
maximum diameter of 4.2 meters. The telescope can
produce images with higher optical resolution of 0.1
arcsec.
7. First we have the “Galaxia del Sombrero”, also called M 104 in the
Messier catalog, distance of about 28 million light years, is considered
the best picture taken by Hubble.
8. Secondly we have the fabulous Mz3 Nebula Ant Nebula called the
garb of the telescopes, located between 3000 and 6000 light years.
9. Thirdly we can see the Eskimo Nebula NGC 2392,
located at 5000 light years.
11. In fifth place we have chosen the Hourglass Nebula located
8000 light years, a beautiful nebula with a narrowing in the
middle.
12. In sixth place we have the Cone Nebula, 2.5 light years.
13. Seventh find a fragment of the Swan Nebula, located at 5500 light
years away, described as “a bubbly ocean of hydrogen with small
amounts of oxygen, sulfur and other elements“
22. Comet Halley has an elliptical orbit, with a focus on the Sun. Its
orbital period is between 74 to 79 years. The last time was seen
from Earth, was in 1986. It is estimated that its next perihelion will
be in 2061.
Named after the astronomer who discovered it, Edmund Halley, in 1705.
Its origin is found in two places: the Kuiper Belt (a flat disk of icy debris
star) and the Oort Cloud (a sphere of cometary bodies, whose inner edge
is located about 50,000 AU)
