    NASA: Lunar Reconnaissance Orbiter makes astonishing discovery

    2/6 NASA Moon recently tweeted, "Lunar Reconnaissance Orbiter images of pits indicate that the Moon has caves. Could they become astronaut habitats? Scientists have discovered that parts of the pits are always about 63°F (17°C), differing from extreme temperatures at the Moon's surface". (NASA)

    3/6 The surface temperatures on the Moon can go from an extremely high 127 degrees Celsius and as low as -173 degrees Celsius. "The pits, and caves to which they may lead, would make thermally stable sites for lunar exploration compared to areas at the Moon's surface, which heat up to 260 F (about 127 C) during the day and cool to minus 280 F (about minus 173 C) at night,” NASA Moon tweeted further.

    5/6 LRO Project Scientist Noah Petro of NASA's Goddard Space Flight Center said, “Lunar pits are a fascinating feature on the lunar surface. Knowing that they create a stable thermal environment helps us paint a picture of these unique lunar features and the prospect of one day exploring them.” (NASA)

    6/6 The particular pit used to analyze the thermal properties by the Lunar Reconnaissance Orbiter was in an area of the Moon known as the Mare Tranquillitatis. It is 100-meters deep and as wide as a football field. According to scientists, the overhang of the pit is responsible for creating shadows on the Moon and maintaining a temperature of nearly 17 degrees Celsius at all times. (NASA)

    Have you seen an image in which two galaxies appear to collide? Well, that is rare. However, you can see the awesome image now. Yes, NASA's Hubble Telescope has captured the same. It can be noted that the galaxies in the image appear to collide, but amazingly, in reality they are not interacting at all. Sharing the image of the galaxies on its official Twitter account, the Hubble Space Telescope tweeted, "It's all about perspective! In this #HubbleFriday image, these two galaxies appear to collide – in reality, they aren't interacting and might be like ships passing in the night."

    In the image the two overlapping spiral galaxies captured by the NASA Hubble Space Telescope are named SDSS J115331 and LEDA 2073461, which lie more than a billion light-years from Earth. "Despite appearing to collide in this image, the alignment of the two galaxies is likely just by chance – the two are not actually interacting. While these two galaxies might simply be ships that pass in the night, Hubble has captured a dazzling array of other, truly interacting galaxies," NASA said while giving insight about the click.

    This image is one of many Hubble observations delving into highlights of the Galaxy Zoo project. Originally established in 2007, Galaxy Zoo and its successors are massive citizen science projects that crowdsource galaxy classifications from a pool of hundreds of thousands of volunteers. These volunteers classify galaxies imaged by robotic telescopes and are often the first to ever set eyes on an astronomical object.

    NASA further informed that over the course of the original Galaxy Zoo project, volunteers discovered a menagerie of weird and wonderful galaxies such as unusual three-armed spiral galaxies and colliding ring galaxies.

    Did you know?

    How much do you know about NASA's Hubble Space Telescope? The Hubble Telescope is a project of international cooperation between NASA and ESA. The Telescope's mirror-based optical system collects and focuses light from the universe to be analyzed by science and guidance instruments. The optical system, called the Optical Telescope Assembly (OTA), gives Hubble a unique view of the universe by gathering infrared, visible and ultraviolet light. However, it has been upstaged by the newer and more powerful James Webb Space Telescope.
