Having up to $500 to purchase a telescope is a good budget, but it can be difficult to spend. It’s too much to buy a beginners telescope, which you can typically find for just a few hundred dollars. However, it’s not enough to purchase a more expensive advanced telescope. You’ll find that there are many … Read more
For those new to astronomy, it can appear to be a bit of a daunting hobby. Just a telescope mount alone can cost hundreds (if not thousands) of dollars, so many people just avoid giving astronomy a chance altogether. However, if you don’t want to spend a ton of money on a telescope, you can … Read more
Any astronomer will tell you how important a good telescope mount is to your success in exploring the night sky. For beginners, the telescope mount is actually something that many people overlook. A good mount is an essential part of your astronomy kit, especially if you’re interested in astrophotography. The first thing you’ll need to … Read more
A good telescope will provide the opportunity to discover all of those heavenly bodies and celestial sights, but a poor choice can simply be money down the drain. Unfortunately, there is no one size fits all solution to answer the question of which is the best telescope for viewing planets and galaxies. This will depend … Read more
A high quality telescope can be an expensive investment in a new hobby, and many people would prefer to purchase something cheaper to gauge their interest. This introduces some new problems; a telescope that costs under $200 may be capable in many ways, but you’re not going to see the rings of Saturn in that … Read more
After you start to take your astronomy seriously, you’ll realise that it can be an expensive hobby to have. Sure, you can get by with a few hundred dollars worth of telescope and the accessories it comes with for a while, but if you want to take the next step up, many top telescopes go … Read more
If your kids have taken a liking to astronomy, then the best way to foster or support an interest is to purchase a telescope for your kids. But, if you’re not familiar with telescopes, this can be an intimidating process. The technical jargon takes some time to learn, and this can make research a frustrating … Read more
Having enough to fuel a large combustion reaction would require an incredibly large tank to contain it, the opposite of what is needed for an aerodynamically designed launch vehicle. Hydrogen, the fuel for the main engines, is the lightest element and usually exists in gas form. Boosters that require continuous cooling, which causes rockets to … Read more
Astronauts also sweat a lot in flight, which means that sex without gravity would probably be hot, humid and surrounded by little beads of sweat. When they went into space together, Lee and Davis even spent some time artificially inseminating frog eggs for the greater good. Despite the arrival of mixed crews in 1983, NASA … Read more
With a radius ranging from 1,530 to 2,550 solar radii, it may probably be the largest star in the Universe if the latter end of the spectrum is closer to reality. With a radius ranging from 1,530 to 2,550 solar radii, it may probably be the largest star in the Universe if the latter end … Read more
According to theory, white dwarfs represent the end point of stellar evolution of main sequence stars with masses between 0.07 and 10 solar masses. Considering the low mass and wide orbit of this object, WD 0806-661 B can be interpreted as a brown subdwarf or direct-imaging exoplanet. Instead, at the end of its life, it … Read more
Rigel was also given the name Gin-waki (銀脇), which means “the silver star next to Mitsu-boshi (Orion’s Belt)”. Although Rigel’s physical properties are uncertain, the star will meet the same fate as other exceptionally massive stars. Some sources classify the star as an outlying member of the Orion OB1 association, but since Rigel is much … Read more
A hypothetical object traveling at the speed of light would take about seven hours to travel around the great circle of UY Scuti, while it would take 14.5 seconds to go around the Sun. This ejection occurred at the time when mankind’s ancestors were learning to walk on two feet. And as long as UY … Read more
You now have the power to choose the right location and firing direction that will give you the Star Trails pattern you need to tell the story you want.

Some of these stars, such as Betelgeuse and Arcturus, are bright enough to notice their colours with the naked eye from moderately light-polluted areas. Red, orange, yellow, yellow, blue and sometimes white. Currently, most stars are classified according to the Morgan-Keenan (MK) system, which classifies stars according to their temperature using the letters O, B, … Read more
This leaves a light closer to the red spectrum, so a moon low on the horizon can sometimes appear more yellow or even pink than one directly overhead. Seeing a star with the Sun in the field of view will never be less difficult than spotting a handful of candles while looking into the beam … Read more
The last quarter moon appears after the full moon. If your finger against the crescent moon makes a “b” shape, then it is waxing (crescent). The rest of the Moon is also sometimes faintly visible during most of this phase because the Earth also reflects sunlight back at the Moon. Interestingly, in this phase the … Read more
A new study claims the basin may contain a huge chunk of metal larger than the Big Island of Hawaii. Although Oceanus Procellarum may or may not be an ancient impact crater, the Moon is covered with impact craters. On the fateful day of its collision, the energy of the impact carved a deep bowl-shaped … Read more
Darwin’s formula can only be reconciled with modern estimates of the Moon’s age and distance if its typical recent recession rate is reduced to about one centimeter per year. Of course, a few billion years after that, the sun will derail the Moon completely, and the Earth as well, when it runs out of fuel, … Read more
In addition, the current angular momentum of the Earth-Moon system was too low to be explained by a rotationally unstable Earth throwing off enough material to form the Moon. This produced a large amount of debris in Earth’s orbit, which in turn coalesced into the Moon. Canup, suggests that the Moon and Earth formed from … Read more
