NASA Astronomy Picture of the Day 19 June 2023: Spooky Lagoon Nebula!

[ad_1] Nebulae are vast cosmic formations consisting of dust and gas -- which originate from various sources, such as the ejected material of a dying star, like a supernova explosion. Moreover, certain nebulae serve as fertile grounds where the birth of new stars begins. That's why, these particular nebulae are often known as "star nurseries." One such nebula is the Lagoon Nebula.Today's NASA Astronomy Picture of the Day is a spooky snapshot of the center of the Lagoon Nebula. In this image, in the heart of the Lagoon Nebula, a breathtaking spectacle of star formation unfolds. NASA has explained that positioned near the center of the captivating image, two elongated, funnel-shaped clouds emerge, stretching about half a light-year in length. These magnificent formations are the result of...

NASA Astronomy Picture of the Day 17 June 2023: Earth at night from ISS

[ad_1] An impressive number of over 14,000 satellites have been successfully launched into near-Earth orbit, United Nations Office for Outer Space Affairs data revealed. Low Earth Orbit refers to a space region situated less than 1000 kilometers above the Earth's surface. It is a preferred orbit for satellites due to its close proximity to Earth and the array of benefits it offers for various applications. Among the well-known things in this orbit is the International Space Station (ISS), a habitable space station renowned for its role as a laboratory for scientific research and fostering international cooperation.NASA Astronomy Picture of the Day for June 17 is a timelapse video of a serene sequence of Earth at night captured by the International Space Station in 2017.

NASA Astronomy Picture of the Day 15 June 2023: M15 Globular Star Cluster snapped by Hubble

[ad_1] Over the past few months, we've seen several amazing images of celestial objects as part of NASA Astronomy Picture of the Day, which is published on a daily basis featuring astrophotographers from around the world. Some of these include snapshots of fascinating celestial objects documented by Charles Messier. The French astronomer studied and catalogued these objects in Catalogue des Nébuleuses et des Amas d'Étoiles and the catalogue is today known as the Messier Objects which contains 110 objects. Today's NASA Astronomy Picture of the Day is a breathtaking snapshot of M15, a globular star cluster that is located about 33600 light-years away towards the constellation of Pegasus. According to NASA, Messier 15 is one of the densest ever discovered, with hot blue stars and cooler or...

NASA Astronomy Picture of the Day 14 June 2023: Stunning Shark Nebula

[ad_1] Nebulae are star-forming regions that have some of the most peculiar shapes, with some of the most fascinating examples being the Headphone Nebula, the Heart and Soul Nebula, and the Flying Ghost Nebula. These star nurseries are located in Interstellar space, which is the space between stars, and consist of gases, mainly hydrogen, and helium. Although most nebulae belong to just three types - spherical, elliptical, and bipolar, some of them might be irregularly shaped, so much so that they resemble objects on Earth. According to NASA, a Nebula can contain as few as ten stars or as many as millions of stars.Today's NASA Astronomy Picture of the Day is a fascinating snapshot of LDN1235, also known as the Shark Nebula, which is located about 650 light-years away towards the constell...

NASA Astronomy Picture of the Day 13 June 2023: Moons crossing Great Red Spot on Jupiter

[ad_1] Jupiter has been shocking astronomers ever since astronomer Galileo Galilei started recording its mysteries as far back as 1610. Jupiter is also known as the Gas Giant as it has a dense atmosphere of hydrogen and helium with windy clouds of ammonia. It is the fifth planet in the solar system, and it is by far the biggest one. In fact, it is twice as big as all the other planets in our solar system combined. It also has the most moons in the solar system, with 92 confirmed moons with orbits, according to International Astronomical Union's Minor Planet Center.Today's NASA Astronomy Picture of the Day is a snapshot of Jupiter's two largest moons, Europa and Io, crossing the gas giant. With a radius of almost 1821 kilometers, Io is the third-largest of Jupiter's four Galilean moons. ...

NASA Astronomy Picture of the Day 11 June 2023: What is the TRUE colour of the Sun?

[ad_1] What Color is the Sun? The answer to this question seems obvious -- yellow. That's what we see on a daily basis, right? But you would be surprised to know, that the true colour of the Sun is not absolute Yellow or even White. Seems confusing? Don't worry, NASA has covered it all! According to the space agency, the colour that we perceive is undeniably influenced by various factors. These include the wavelength and intensity of the light being emitted, environmental conditions, the capabilities and restrictions of our eyes in capturing light, and ultimately, the functioning of our brains.Today's Astronomy Picture of the Day is actually the colour spectrum of the Sun. However, there are some missing colours too! The spectrum shared by NASA has the complete range of observable colou...

NASA Astronomy Picture of the Day 9 June 2023: Webb Telescope snaps Pandora Cluster

[ad_1] Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. Galaxies exist in the vastness of space, consisting of various celestial objects such as stars, clouds of dust, and gas, all of which are bound together by gravity. These galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.Today's NASA Astronomy Picture of the Day is a snapshot of Abell 2744, also known as the Pandora's Cluster of galaxies which is located about 4 billion light-years away towards the constellation of Sculptor.
