What do Astronomers do?
In general, astronomers seek an understanding of how the Universe works; from the planets in our own Solar System, to the evolution of stars and nebulae, to whole systems of galaxies, to the properties and fate of the Universe as a whole. Modern astronomy is an interdisciplinary science that relies upon, and furthers the development of, fields such as physics, chemistry, computer science, and mathematics.
Only the very nearest astronomical objects (all within our Solar System) can be reached by spacecraft in a reasonable amount of time. Information about all other objects comes indirectly from earthbound telescopes or earth-orbiting satellites, which observe light emitted or reflected from such objects. The collection and detailed analysis of this light is key to unlocking the mysteries of the observable Universe. The sole purpose of a telescope is to collect this light; it is the role of the astronomer to analyze and interpret this data.

What did early astronamors think of Venus before probes explored Venus?
Good question. Astronomers, believe it or not believed that venus had life since it is Earth's twin planet.
Do volcanoes only erupt on earth?
No, Astronomers have discovered erupting volcanoes on Venus as well as Earth
What astronomers landed on the planet Venus's?
No, and it is doubtful they ever will. The environment on Venus is extremely hot, the atmosphere is extremely thick, and has acid in it. It is very difficult to even build robots that can stand up to it for more than seconds before they quit working.
Do astronomers know what the surface of Venus is like?
Yes, astronomers have gathered data on Venus's surface using spacecraft missions and radar imaging techniques. Venus's surface is extremely hot, with temperatures reaching around 900 degrees Fahrenheit, and pressure over 90 times that of Earth's. It is covered in volcanic plains, mountains, and large impact craters.
What evidence leads astronomers to believe that Venus is geologically young?
Astronomers believe Venus is geologically young because it lacks significant impact craters compared to other planets. This suggests that its surface has been recently resurfaced by volcanic activity, which erases older impact features. Additionally, Venus's lack of tectonic plate movements and volcanic activity may indicate a relatively recent geological history.
What did astronomers call Venus?
Phosphorus

What does Greek astronomers have to say about Venus?
Well Venus is the Roman word for the Greek goddess Aphrodite. I think they would have liked it if Aphrodite was the name for a lovely planet instead of Venus.
Why can't photos be taken of Venus?
The planet Venus has been photographed by astronomers. Due to the heavy cloud cover, it appears to be a featureless orb.
Do volcanoes only erupt on earth?
No, Astronomers have discovered erupting volcanoes on Venus as well as Earth
Why can astronomers see the surface of mars clearly not the surface of Venus?
Surface materialsbasaltic rock and altered materials

Was Venus unknown to the ancient Greeks?
Venus is easily seen in the sky without any telescope, so it was well known to ancient astronomers in Greece and elsewhere. The Ancient Greeks knew of Venus, they called it Φωσφόρος (Phosphoros).

Is it true or false that Astronomers on Earth are able to measure the rotation of Venus by using optical telescopes to watch surface markings as rotation carries them across the disk of Venus?
True
Is the transit of Venus's easy to see?
The transit of Venus is very easy to see. It is widely viewed, especially by scientists and astronomers around every century. The next transit of Venus shall occur in the year 2012 AD. -DATE: 15.6.11
What do astronomers use to measure planets?
Planets' sizes are measured from their angular width as seen from the Earth. The basic scale of distances is calibrated by measurements of Venus from different points on Earth at the time of a transit of Venus.
