Venus was shining so bright that my boyfriend told me to come to the window to look at it. We got our binoculars out and used an app to determine that it was Venus. About 20 minutes later my boyfriend went to another room in the apartment and I was sitting on the couch, still looking out the window at Venus, when suddenly it started moving.
First I thought my eyes were playing tricks on me but it kept moving until it was out of my line of vision completely. I called my boyfriend and said "come here, it moved. So bizarre. But if your app says it's Venus, it probably is, or maybe you were witnessing International Space Station? Are you sure it was not a cloudy night? And perhaps the shiny object was camouflaged by a big cloud? Happens to me a lot. Add a comment.

It can't be it, since it said on that particular night it was not visible at all. A mountain wave is a type of atmospheric gravity wave created by topographical elements like mountains and the way wind flows over them. Venus' surface is difficult to image not only because of the planet's varying rotation, but also because the surface is "hidden behind a permanent, thick cloud cover," Thomas Navarro, study author and researcher at the University of California, told Space.
This has made it especially difficult for researchers to understand this phenomenon. However, by using pictures at various wavelengths from Akatsuki, the researchers in the new study were finally able to get a clear image of the bow-shaped structure and confirm the presence of a mountain wave.
They also explained how mountain waves cause Venus to spin at varying speeds: Because of the different directions of the wind flowing upstream and downstream against the mountain, "Overall, a net force is exerted on the mountain, and the whole solid body follows," Navarro said.
By learning about Venus' mountain waves, scientists can better "understand how angular momentum is transferred between the solid body [of Venus] and the atmosphere," Navarro said. This is not only the slowest rotation period of any planet, it also means that a single day on Venus lasts longer than a Venusian year.
Technically, this means that its rotational period is , days. It also means that if you could view the Solar System from the position above its celestial north pole, all of the planets except for Uranus, which rotates on its side! Venus, however, would appear to be rotating in a clockwise direction. Because of this, if you could stand on the surface of Venus, you would witness the Sun rising in the west and setting in the east. But you would be waiting a very long time to see this happen!
Read on to find out why…. Another important thing to consider is the difference between a sidereal day and a solar day. A solar day, by contrast, refers to the amount of time it takes for the Sun to reappear at the same point in the sky i. A Venusian aka. Cytherean Solar Day is the equivalent to Doing the math, we then see that a single year on Venus Not exactly the basis for a good calendar system, is it? Yes, when it comes to the planet Venus, things work quite differently than they do here on Earth.
This page showcases our resources for those interested in learning more about Venus. Venus Resources. Ten Mysteries of Venus. JPL's lucky peanuts are an unofficial tradition at big mission events. Full Moon Guide: October - November A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought. This year, the minimum extent of Arctic sea ice dropped to 1. The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes.
Researchers will use Webb to observe 17 actively forming planetary systems. Scientists found evidence that an area on Mars called Arabia Terra had thousands of "super eruptions" over a million-year period. Full Moon Guide: September - October Perseverance successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region.
Data received late Sept. The rover will abrade a rock this week, allowing scientists and engineers to decide whether that target would withstand its powerful drill.
Drought is a complicated problem that requires lots of data. Satellites from NASA and its partners help collect that data. Drought Makes its Home on the Range. Gene Roddenberry would have been years old on Aug. Full Moon Guide: August - September The images show Venus approaching from the left while the Sun is off-camera to the upper right.
The next full Moon goes by many names including the Buck Moon. Full Moon Guide: July — August The probe flew closer to Jupiter's largest moon, Ganymede, than any other spacecraft in more than two decades. The balloons are being developed to detect venusquakes. In , they made the first balloon-borne detection of a quake much closer to home. These locations are called planetary analogs.
