NASA highlights: Astronomical photos of the week (June 3rd to July 9th, 2021)

Published

on

Another Saturday is here, and you can already check out which astronomical images NASA has selected in the past few days. This week you will find records of nebulae as colorful and impressive as that of Orion, which has a “star nursery” inside. Also, check out a few of Saturn’s moons – specifically six of the 80+ moons orbiting the gas giant.

By the way, since it is one of the planets in the solar system, it is worth noting that you can also find a very interesting picture of Mars. This is an old image taken by NASA’s Viking 2 spacecraft in the 1970s. Even after so long, this photo still plays a trick on our brains that identifies a shape resembling a face, in the middle of a rock shadow on the surface of the Red Planet.

Check out these and other images below:

Saturday (3) – Milky Way

The glow of the Milky Way in the night sky has fascinated observers from the most varied of eras and generations. The Italian astronomer Galileo Galilei, for example, pointed his telescope at the luminous band he saw in the sky and described the scene as “a collection of innumerable stars”. We still don’t know exactly how many stars there are in our galaxy, and it is currently estimated that they are around 200 billion, but that number could reach 400 billion.

Only a minimal amount of this can be seen with the naked eye: Only 0.000003% of our neighboring stars are visible! In any case, Galileo’s speech is clear to anyone who can admire the clear night sky and somewhere far from light pollution. Even with the naked eye, it is possible to find the glowing and pale “path” of our galaxy, which is criss-crossed by dark clouds of dust.

Sunday (4) – The “face” of Mars

You may have seen clouds of strange shapes in the sky that resembled an animal or object, and you may also have been intrigued by the “face” in the picture above. Situations like this are caused by a phenomenon called pareidolia, which is our brain’s ability to recognize patterns – it helped our ancestors differentiate between dangerous plants and animals, stay away from predators, and find food.

By the way, pareidolia does not only appear in what we see on Earth, and proof of this is this photo, which was taken on the Red Planet. The picture was taken in the 1970s by the old Viking spacecraft and shows a geological formation called the “table”. Depending on the angle of incidence of the light, the shadows formed look like a nose and a mouth. In addition to the low resolution, there are also many black dots in the photo, errors that are caused by incorrect transmission of the data.

Monday (5) – The Blue Horsehead Nebula

Here we have the Blue Horsehead Nebula. Located in the constellation Scorpio, the Scorpio, it is made up of very fine dust that is usually dark but shows a bluish glow as it reflects visible light emitted by nearby stars. In this case the luminosity comes from a star in the “eye” of the cloud horse, which is part of the Nu Scorpii system, one of the brightest, in the direction of the constellation Scorpio. On the right side of the picture is IC 4601, another reflection nebula.

Tuesday (6) – Moons of Saturn

Today we already know 82 moons of Saturn. Of these, six appear in this composite image, which was captured with 13 images of the planet and another 13 of the brightest moons in its orbit. The first moon to be discovered in the orbit of the gas giant was Titan, identified in 1655 by the Dutch astronomer Christiaan Huygens; here it almost seems to complete a round of the planet. Titan has a diameter of 5,150 km, making it the largest in the system – for comparison: This moon is even larger than Mercury, which has a diameter of 4,879.4 km! The moon Reia is the second largest while Jápeto is considered the third largest and the origin of the path is also in the right corner of the photo.

Wednesday (7) – Orion Nebula in detail

About 1,600 light years away from us, in the constellation Orion the Hunters, is the Orion Nebula. This nebula is known for its brightness, which makes it easy to see even with the naked eye. However, if you want to admire it in a different way, a good option is the animation shown above, which made a digital model using data from the Spitzer telescope applied to video rendering techniques.

As a result, we have the details of the stellar nursery in the heart of the nebula, with baby and young stars in various stages of development. Then the camera moves through this molecular cloud until it reaches a cavity formed by energetic winds together with the radiation from the large stars in the trapezium cluster at a very high temperature.

Thursday (8) – aphelion and perihelion

As the earth moves in an elliptical orbit around the sun, our planet occasionally traverses the most distant and closest points of our star. One such moment happened at the beginning of the month: in early July, the Earth passed the point furthest from the Sun, and our star had the smallest apparent size. In perihelion, on the other hand, the moment of closest proximity, the star appears larger – and you see both situations in the above image, which consists of two photos taken with the same telescope and the same camera.

It is worth remembering that the variations in the distance between the earth and the sun are not responsible for the seasons, but for the inclination of our planet. Since the earth is tilted 23.4 ° from the orbital plane, sunlight falls on the hemispheres in different ways. At the moment as the northern hemisphere goes through summer, we are getting less direct heat and this will be reversed in six months. Both hemispheres receive a similar amount of warmth in spring and autumn.

Friday (9) – Winds in the Cigarette Galaxy

Galaxy M2, also known as the Cigarette Galaxy, is a great place to find some intense processes. There is a superwind emitted in the central regions of the galaxy where a large number of stars are also forming at an impressive rate – some of them forming a rate 10 times faster than that of our own galaxy! This star factory should run at full speed for at least 100 million years.

This is a composite image that shows some interesting details from the superwind. Notice that there are some reddish filaments in the center of the image. They look like tiny rays and are actually light emissions in atomic hydrogen that glow red. Over time, some of the superwind gas will “escape” from there and travel into intergalactic space.
