Can i see venus in the night sky




















Some, like Mercury and Mars, are lower, but Venus has an albedo of 0. The dramatic brightness may evoke images of the goddess of beauty on Earth, but it's caused by conditions that more resemble Hades than Heaven. Venus has a thick cloud cover, and the clouds don't contain any life-giving gases, such as oxygen or water vapor. They contain contain a mixture of carbon dioxide and sulphuric acid, and they are so dense that the atmospheric pressure at the surface is about 90 times what it is on Earth.

At degrees F degrees C , the surface temperature is hot enough to melt lead. No human could survive there, and even mechanical probes don't last long.

None of the Soviet Venera probes that reached the surface in the 20th century lasted longer than an hour. With boiling temperatures and sulfuric acid rain, it's an understatement to say that the weather isn't very good on Venus.

The answer is no, but the agency has sent exploratory probes. Mariner 2 flew within 34, kilometers of the planet in , and Pioneer Venus orbited the planet in to study, among other things, its solar wind. Magellan, launched in , orbited the planet and mapped 98 percent of the surface by radar. Up until now, the U. For their part, the Russians have announced no plans to send another probe to Venus, but that doesn't mean they won't.

Other space agencies have sent probes to Venus, however. It orbited the planet for eight years, studying, among other things, how Venus lost its water. Spoiler alert: There's a good chance the solar wind did it. The Akatsuki spacecraft encountered problems on its journey, however, and had to spend five years orbiting the sun before it successfully dropped into orbit around Venus on Dec.

It continues to send back data about topography and climate. The extreme build-up of carbon dioxide in Venus' atmosphere is largely responsible for the hellish conditions on the planet. There's a natural tendency for Earth dwellers to take that as a warning, given the rapid increase of carbon dioxide in our own atmosphere. The warning is worth heeding, but it's important to remember that Venus and Earth are two very different places.

The data we have received from probes such as Magellan, Venus Express and Akatsuki confirm this. The surface of Venus, unlike that of Earth, is ridden with volcanoes.

Many are still active and spew gases into the already poisonous atmosphere. The surface is dry. Sulfuric acid rain does occur in the upper atmosphere, but it evaporates before it hit the ground. Water exists only in trace amounts. It's possible it simply boiled away into space, but the ESA discovered another mechanism that may account for the complete lack of water on a planet that scientists believe used to have as much water as Earth.

The Venus Express probe discovered that hydrogen gas is continuously stripped from the day side of the planet and radiated into the space on the night side. This effect is caused by the solar wind, which is much stronger on Venus that it is on Earth due to Venus's proximity to the sun. Together, rising temperatures caused by CO 2 buildup and the effects of the solar wind could have turned Venus into the inferno it is today.

It's unlikely the same thing would happen in the exact same way on Earth. Venus can best be seen in the hours just after sunset. Visibility improves as the sunlight fades. Venus is visible by day, but may be hard to find. Mars is just 11 degrees from the Sun in the sky, so it is difficult to see. Saturn can best be seen in the hours just after sunset.

Uranus is roughly in the opposite direction of the Sun, so it is visible during most of the night. You may need binoculars. Very faint, use binoculars. See how far the planets are from the Sun or Earth, how bright they look, and their apparent size in the sky.

Dates and tips on how and where to see "shooting stars" from meteor showers all over the world. A conjunction is when planets like Mars, Jupiter, or Saturn, or other bodies like stars or the Moon, meet in the sky. Why and when do conjunctions happen? Venus remains an early-morning lantern in the east-southeast a couple of hours before sunrise all month long, while Mercury enjoys a splendid morning apparition.

In our schedule, remember that when measuring the angular separation between two celestial objects, your clenched fist held at arm's length measures roughly degrees. Here, we present a schedule below which provides some of the best planet viewing times as well directing you as to where to look to see them. Remember on Nov. On this date, the clock hour from 1 a. The mnemonic is: "Spring Ahead, Fall Back. Mercury — enjoys its very best morning apparition of this month.

Each morning thereafter it rises a couple of minutes earlier, climbs noticeably higher and also gets noticeably brighter. On Nov. For several mornings both before and after this date, Mercury will appear to rise prior to the onset of twilight, in a dark sky, about 1 hour 45 minutes before sunup.

At a brilliant magnitude of At around 5 a. After greatest elongation, Mercury will slide rapidly back toward the sun. By the 24th it's again rising about 75 minutes before sunrise, but still should be bright enough
