# How to see Mars and Venus in color?

My telescope is Arsenal - Synta 70/700 AZ2 (refractor model). 140x max zoom (10 mm with Barlow). I could clearly see Jupiter and Saturn in color. I even saw brown stripes on Jupiter. Yet, when I tried looking at Venus and Mars they appeared pure white, totally washed out by the Sun. I was observing about hour before sunrise.

Is there a way to see them in true color with my current tech? Maybe they could be seen only at certain dates? Or maybe I need some filters?

You are seeing them in color, it's an issue of the mechanics of your eyes. Eyes are made of rods and cones, cones seeing color, rods seeing greyscale. When you are looking through a telescope, your eye adapts to the low light conditions and the rods dominate the sensitivity.

Jupiter appears much larger than both Mars and Venus, so your eye does not adapt as much and the cones relay more information, allowing you to perceive more color for both it and Saturn (which is also larger than both Venus and Mars in our sky).

That said, Mars through a telescope, to me, appears a bright orange. Venus, to me, is indistinguishable from white, though it should look more of a pale yellow since that is its color in visible light.

You could try looking when the sky is darker, for Mars is visible in the middle of the night. It's possible that the blue of the sky is affecting your color perception, too. Venus is always a morning or evening object, so you should try looking at it just a little after it has risen (looking at it just as it rises will result in atmosphere issues).

## How to see Mars and Venus in color? - Astronomy

The Moon and Mercury are geologically dead. In contrast, the larger terrestrial planets—Earth, Venus, and Mars—are more active and interesting worlds. We have already discussed Earth, and we now turn to Venus and Mars. These are the nearest planets and the most accessible to spacecraft. Not surprisingly, the greatest effort in planetary exploration has been devoted to these fascinating worlds. In the chapter, we discuss some of the results of more than four decades of scientific exploration of Mars and Venus. Mars is exceptionally interesting, with evidence that points to habitable conditions in the past. Even today, we are discovering things about Mars that make it the most likely place where humans might set up a habitat in the future. However, our robot explorers have clearly shown that neither Venus nor Mars has conditions similar to Earth. How did it happen that these three neighboring terrestrial planets have diverged so dramatically in their evolution?

Figure 1. Spirit Rover on Mars: This May 2004 image shows the tracks made by the Mars Exploration Spirit rover on the surface of the red planet. Spirit was active on Mars between 2004 and 2010, twenty times longer than its planners had expected. It “drove” over 7.73 kilometers in the process of examining the martian landscape.

## When do conjunctions occur?

Often a conjunction will occur during daytime or when the objects are below the horizon, and this is where the definition becomes more relaxed.

If the objects are very bright, such as a crescent Moon and Venus, then daylight viewing can be possible, but if the objects have set below the horizon they won’t be visible.

So conjunction can be applied in quite a loose context to refer to objects that are viewable above the horizon in twilight or at night, even if they are not, at that point, at the exact moment of conjunction.

• If the objects are at their closest, then this is known as an appulse: the minimum separation between two bodies that occurs just before or after true conjunction.

Conjunctions really capture our attention, which makes them ideal targets for public stargazing events, or for inspiring young astronomers and newcomers to look up at the night sky.

They are also easy to capture with a smartphone camera, giving more people the chance to preserve the moment and share with friends or on social media.

## 3. March 28, April 27, May 26, June 24, 2021: Supermoons – Quarterly

A supermoon is a spectacle that occurs when a full moon is at perigee, the point where the Moon is closest to Earth during its orbit. At this point, the Moon will appear 14% larger and cast nearly 30% more light. (Beware of the super-werewolves on this date!)

This year, there will be four supermoons (which is the typical annual amount). They will occur on March 28th, April 27th, May 26th, June 24th, with the moon on May 26th appearing to be the biggest and the brightest.

### How can you see it?

Because it is so bright, a supermoon won’t be too hard to spot! Keep your eyes near the horizon, and you’re sure to be blown away.

### What will it look like?

You can’t miss it! A supermoon is an incredibly bright, full moon illuminating the night sky and everything beneath it!

## June Astronomy: As the Summer Begins, Mars and Venus Engage in a Cosmic Dance with Pollux and Castor

Fast-moving Mars and Venus make eye-catching arrangements with Pollux and Castor this month, before the twin stars’ annual departure into the evening twilight glow. Even the slow motions of Jupiter and Saturn can be noted with careful attention to background stars.

The moon pairs up with four of the five naked-eye planets and four of the five zodiacal first-magnitude stars. Venus presents its northernmost setting of 2021 on June 4, 16 days before the sun does so. The aptly named Summer Triangle is visible from dusk until dawn from late June until early August.

In June’s evening twilight: The only planets visible at dusk are bright Venus, of magnitude -3.8, very low in the west-northwest, and faint Mars, of magnitude +1.8, some 25 to 7 degrees to Venus’ upper left. The brightest stars visible, both of zero magnitude, are golden Arcturus, very high in the southeast to south-southwest, and blue-white Vega, climbing high in the east-northeast.

In early June, the Spring Arch of four stars is still visible: Procyon, low in the west twins Pollux and Castor, atop the arch and 4.5 degrees apart in the west-northwest and Capella, low in the northwest. The twins remain visible at month’s end, but only with the aid of binoculars.

Watch for these striking arrangements of planets with twin stars Pollux and Castor: Mars, on June 7, is 7 degrees to the left of Pollux and forms a straight line with the twins. Venus, on June 13, forms an isosceles triangle with the twins. On June 21, Venus passes 5.2 degrees to the south (lower left) of Pollux, its least distance from that star. On June 24, Venus is 6.5 degrees to the left of Pollux and forms a straight line with the twins.

Other stars visible at dusk: Regulus, heart of Leo, is in the west-southwest to west, to the upper left of Venus and Mars. (Mars closes to within 18 degrees of the lower right of Regulus at month’s end.) Spica, the spike of grain in the hand of Virgo, crosses through south into south-southwest, 33 degrees to the lower right of or below Arcturus. Antares, heart of the Scorpion, starts very low in the southeast and climbs into the south-southeast. Look for Deneb to the lower left of Vega. Watch the horizon a little more than 10 degrees north of east, to Vega’s lower right, for the rising of Altair, completing the Summer Triangle with Vega and Deneb.

Follow the moon for two weeks as it waxes from a thin crescent on June 11 to full on June 24. Watch for its pairings with planets and bright zodiacal stars on the evenings of June 11 (Venus) 12 (Pollux) 13 (Mars) 15 (Regulus) 19 (Spica) and 22 (Antares).
