Cool facts about the universe

1 Jan

It’s not easy getting to know the entire Universe because it is full of complexities that can’t even be explained. Us humans know merely the surface of this gigantic thing and whenever we get the opportunity to see images and learn new facts, we can’t stop our endless contemplation. Due to so many worldwide organizations that seek to explain things about space, we are able to find out what really goes on in our world that goes on beyond planet Earth.

One cool fact relates to the sky that we are so eager to watch whenever we’re in a nostalgic or romantic mood. In case you didn’t know, the stars you see at night are so far away from you that it has taken a long time for them to travel across the entire space, before letting us engage in a stargazing session.

Basically, whenever we look up at the ski we are looking in the past because this is how stars looked then. For instance, Vega is a bright star that is somewhat close to the Earth, at only 25 light-years distance. This means that we get to see the light that left Vega 25 years ago. Many stars that we admire are so further away that the image in front of our eyes is way deep in their past.

Another interesting fact is that thanks to the Hubble telescope, we are allowed to look back almost billions of years into the Universe past. This remarkable piece of tool developed by NASA has given us so many amazing images that display a small patch of the sky in full detail. We now know a lot about more than 10,000 objects such as small galaxies and we can be transported 13 billion years back, which is quite fascinating.

Believe it or not, but the biggest mountain in our solar system is located on Mars. Known as Olympus Mons, this tall mountain is, in fact, a gigantic volcano quite similar to the ones from the Hawaiian Islands. It is 16 miles tall and sprawls at a distance of almost 400 miles. If you’re not certain how much is this, just imagine a mountain that is 3 times bigger than the Everest.

We all complain about the time and how we barely manage to get our things done in one single day. Crazy as it may sound, a year on the planet Venus is shorter than one day spent there. Because Venus has a slow rotation in our Solar System, it takes less to complete its orbit that to make a full rotation. This translates to days that are longer than an actual year. If you’re planning to move to Venus, think twice. You’ll have to get used to electronic storms, clouds with sulfuric acid, and high levels of CO2.

 

5 things you didn’t know about the moon

11 Nov

 

The Moon is with us every single moment even when we don’t notice. It’s responsible for making our nights brighter, provides support for the tidal activity, and gives a beautiful Lunar Eclipse to admire in full splendor from time to time. Nevertheless, there are some cool facts about the Moon that you probably didn’t know. Keep reading and see what’s the big fuzz about.

The Moon doesn’t orbit the Earth.

Not only it doesn’t orbit the Earth, in fact, it travels at almost the same pace as our planet does. It either travels behind or ahead, depending on the Earth as it revolves around the sun.  

Basically, the Sun has full command over the moon’s motion. The reason we think faulty is that we see it that way from our perspective. During the full moon, the Moon is opposed the sun, and then, after a two-week period, it casts a shadow on the Earth, while being in the same direction as the sun.

We are missing the fact that, over the course of a year, the moon does not loop around the Earth while it goes around the sun. Instead, it moves in tandem with our planet.

 

It used to be a part of Earth.

According to some theories belonging to modern astrophysics, the Moon formed from a material that used to belong to Earth a long time ago. When our planet was very young, an object having a size almost identical to Mars, slammed the Earth and created a large amount of planetary material that wandered through space. It stayed around the Earth until it took a form and created the Moon. It looked a lot different back then because of the molten surface hit by meteors. Thanks to the Moon, we are protected from impactors.

 

It would take hundreds of thousands of moon to get to the sun’s level of brightness

Since the Moon shines with a magnitude of -12.7 and the sun has one of -26.7, it’s clear that the ratio of brightness belonging to the sun is way bigger than the one owned by the Moon. So, you’ll need tons of moons if you want to equal the brightness caused by the sun. Basically, we don’t have that much space to fit all those moons in the sky.  

The Moon has its own time zone.

If you weren’t aware of, there’s a thing called lunation which is the equivalent of 29.530589 Earth days. Therefore, the lunar time is quite similar to the standard time zone we use on Earth. The only difference is that it is based on 12-degree meridians. Plus, a lunar year has 354 Heart days.

 

The Earth’s atmosphere is responsible for the color of the Moon.

During lunar eclipses, the only sunlight that gets close to the Moon is what passes through our planet’s atmosphere. Once the filters refract the sunlight, red is the only color from the spectrum that leaves behind, giving the Moon the same effect as sunsets. If there was no atmosphere on Earth, the moon would go pitch black during lunar eclipses.

 

 

Quality telescopes for beginners

8 Oct

 

If you want to become an amateur astronomer and you need a proper tool to enjoy your stargazing session, you should get a quality telescope. Because there is a vast array of telescopes and accessories available on the market, you might face a tough decision. Therefore, we’ve got some cool tips regarding the basics of how these tools work.

Before you make a purchase, you must determine what features matter most to you and how often you intend to use this type of spectating device. There are certain factors that have an impact on your viewing experience. For instance, it’s not the same if you only have spare time to do this activity during the day or at night.

Also, you need to be aware of your budget limitations. If you plan on becoming an expert in the field, you’ll need to spend more. Beginners tend to overlook the storage as well as the weight of the telescope. Not all units are equipped the same and some of them are more practical than others.

One technical aspect that you need to consider is the aperture of the telescope. This is a component quite discussed by most stargazing enthusiasts and it refers to the diameter of the telescope’s mirror or lens. Also, it gives you details about the quantity of light the unit lets in and the capacity of providing sharp images for the viewer.

The reason why aperture is so important is that this feature is a correspondent for the strength and power of the telescope. Multiple telescope reviews recommend choosing for a smaller aperture because bigger ones are equal with an expensive and bulkier item.

Another element of great importance when in the market for a top-notch telescope is the magnification. Even though you might be tempted to think that a powerful magnification brings the objects closer to your eyes, hence, you get to see clearer; in reality, a larger magnification doesn’t allow you to see the images in a better quality. This happens because a big amount of light is dispersed over a large area so the images get blurred and not crystal clear.

 

When choosing a good telescope and you don’t know much about this type of units, you must take into consideration the eyepiece. They determine the magnification power and the field of view of the product. Some bargain deals such as Meade telescopes provide good features, even high-quality eyepiece, without costing a fortune.

Even if you have a bigger budget, don’t get the largest or the biggest telescope that you encounter. People that use them on a regular basis know that smaller units are more manageable. Aside from that, if you’re just starting to learn the planets you really don’t need all the advanced features until you become more familiar with astronomy.
