NASA Astronomy Picture of the Day 7 June 2023: Breathtaking Double Ring Galaxy

[ad_1] Just a couple of days ago, we saw a breathtaking snapshot of the Trifid Nebula, the 20th object discovered by the French astronomer Charles Messier. Similar celestial objects were studied and catalogued by Messier in Catalogue des Nébuleuses et des Amas d'Étoiles and the catalogue is today known as the Messier Objects which contains 110 objects. 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.Today's NASA Astronomy Picture of the Day is a snapshot of M94, also known as the Double Ring Galaxy that contains over 40 billion stars. According to NASA, the Double Ring Galaxy is located about 15 million light-years away tow...

NASA Astronomy Picture of the Day 30 May 2023: The awesome Dumbbell Nebula!

[ad_1] Over the past few months, we have witnessed several breathtaking but peculiarly-shaped nebulae, as part of NASA Astronomy Picture of the Day which is published on a daily basis. 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. Some of the most peculiar shapes include the Headphone Nebula, the Heart and Soul Nebula, and the Flying Ghost Nebula. For the unaware, a nebula is a star-forming region located in Interstellar space, which is the space between stars. It consists of gases, mainly hydrogen, and helium.Today's NASA Astronomy Picture of the Day is planetary nebula M27, also known as the Dumbbell Nebula, which is located about 1360 light-years away tow...

Earth has a 2nd moon! Amazing 65-foot asteroid just found by Pan-STARRS telescope

[ad_1] Astronomers have discovered a new asteroid that has been orbiting Earth, acting as a "quasi-moon" of our planet. Yes, it is being called the Earth's second moon. This asteroid, named 2023 FW13, has a unique and complex orbit that extends halfway between Mars and Venus, according to David Chandler of Sky & Telescope.The asteroid was first detected on March 28 by astronomers using the Pan-STARRS survey Telescope, located on top of Haleakala, a dormant volcano in Hawaii. The Canada-France-Hawaii Telescope, as well as the Kitt Peak National Observatory and Mt. Lemmon SkyCenter in Arizona, later confirmed its existence. The official announcement of the discovery was made in April. The news caught the attention of Adrien Coffinet, a journalist from the French news website Futura - ...

NASA Astronomy Picture of the Day 19 May 2023: M63 Spiral Galaxy shot by deep-sky imaging camera

[ad_1] Over the past few days, we have seen NASA publish mesmerizing snapshots of celestial objects as part of its daily Astronomy Picture of the Day. But how does NASA capture these objects that are located millions of kilometers away in space? The space agency uses its advanced telescopes such as Spitzer Space Telescope, the Hubble Space Telescope, and the newly launched James Webb Space Telescope. One of the most visually appealing celestial objects captured by NASA is spiral galaxies. These types of galaxies have winding spiral arms that make them look a little like massive pinwheels.Today's NASA Astronomy Picture of the Day is a snapshot of the M63 Curly Spiral Galaxy located about 30 million light-years away towards the constellation Canes Venatici. Also known as NGC 5055, this sp...

Man snaps 280000 images to create one awesome image of the Moon

[ad_1] American astrophotographer Andrew McCarthy has shared an incredibly detailed image of the moon on social media. The image showcases hardened lava lakes, worm-like collapsed lava tubes, permanently shadowed valleys, and impact crater patterns on the Moon's surface.The photograph showcases the moon's surface with exceptional clarity, revealing even the smallest features. McCarthy explained the process behind capturing these stunning images, stating, "By using two telescopes and taking over 280,000 photos, I managed to capture the most detailed image of our moon. The full-sized image is over a gigapixel. Believe me, you'll want to zoom in on this one." After dedicating two weeks to this attempt , McCarthy confidently presents these highly detailed lunar photographs. He jokingly warn...

NASA Astronomy Picture of the Day 24 April 2023: What Star Death left behind-a Supernova

[ad_1] When a star explodes during its death throes, it is known as a Supernova and it is the largest explosion to occur in space. According to NASA, a supernova happens where there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova. Although a supernova occurs for only a short span of time, it can tell scientists a lot about the universe. By studying supernovas, scientists have also shed light on the fact that we're living in an ever-expanding universe.Today's NASA Astronomy Picture of the Day is CTB-1, also known as the Medulla Nebula Supernova Remnant. It is a rare cosmic bubble and the remnant of a supernova explosion which occurred just 10000 years ago, according to NASA. The Medulla Nebula Supernova Remnant i...

Scientists unveil new and improved ‘skinny donut’ black hole image

[ad_1] The 2019 release of the first image of a black hole was hailed as a significant scientific achievement. But truth be told, it was a bit blurry - or, as one astrophysicist involved in the effort called it, a "fuzzy orange donut."Scientists on Thursday unveiled a new and improved image of this black hole - a behemoth at the center of a nearby galaxy - mining the same data used for the earlier one but improving its resolution by employing image reconstruction algorithms to fill in gaps in the original telescope observations. Hard to observe by their very nature, black holes are celestial entities exerting gravitational pull so strong no matter or light can escape. The ring of light - that is, the material being sucked into the voracious object - seen in the new image is about half t...

NASA Astronomy Picture of the Day 28 March 2023: Extremely Rare Green Flash Sunset

[ad_1] Various natural phenomena grace the sky often. One of the most common occurings are auroras, which occur because of Geomagnetic storms impacting Earth. However, there is one more phenomenon which occurs, and it is much rarer. As the Sun sets on the horizon and disappears from view during sunset, sometimes a green flash may appear. It is a meteorological optical phenomenon which may occur for a short period of time during sunrise or sunset. According to NASA, the green flash is caused by refraction of light rays traveling to the eye over a long path through the atmosphere.Today's NASA Astronomy Picture of the Day is a mesmerizing snapshot of a multiple green flash sunset captured from the Cerro Tololo Inter-American Observatory in Chile last April. It was captured by T. Slovinsky ...

Find the mystery asteroid! ESA sends Christmas challenge over humongous asteroid

[ad_1] The ESA has thrown a Christmas challenge for astronomy enthusiasts and has asked them to find a 262-foot wide mystery asteroid which will come dangerously close to the Earth. It is called the Christmas asteroid. The 12 days of Christmas have begun and while many are preparing for the festivities, the European Space Agency (ESA) is adding to the excitement with its Christmas challenge. It has thrown a strange ‘Christmas challenge' for all the astronomy fans across the globe. And the challenge is to find a mystery asteroid floating around space. It is being called the Christmas asteroid. But this is not just a fun challenge, there is a terrifying fact underlying this space rock. It will make a dangerously close approach to the Earth on December 15 and there is always the fear tha...
