NASA’s James Webb Space Telescope captured a stunning image of HH 30, an edge-on protoplanetary disc located in the dark cloud LDN 1551, also known as the Taurus Molecular Cloud, located 450 light-years from Earth. Herbig-Haro objects like this one are basically small nebulae found in star formation regions, marking the locations where gas flowing out from young stars is heated into luminescence by shockwaves.
The Bullseye Galaxy, classified as LEDA 1313424, is located 45 million light-years from Earth, and this Hubble observation shows us its nine rings in all their glory. For comparison purposes, our own Milky Way galaxy spans about 100,000 light-years in diameter, while the Bullseye is almost two-and-a-half times larger, at 250,000 light-years across.
NASA / ESA’s Hubble Space Telescope observes a sparkling supernova within its host galaxy LEDA 132905, located more than 400 million light-years from Earth in the constellation Sculptor. The bright white dot that you see directly in the middle of the image, between the bright center of the galaxy and its faint left edge, is the supernova named SN 2022abvt.
Metal Ball Studios put together an interesting video showing how real comets would compare in size to objects on Earth, more specifically, New York City. Starting off, we have Comet Tsuchinshan-ATLAS, also known as C/2023 A3, which is a comet that was first discovered in 2023.
The American Astronomical Society (AAS) wants the government to limit space advertising before it really takes off, possibly within this decade. They believe that humanity’s scientific understanding of the universe depends on clear and unobstructed views of the cosmos, an enterprise currently under threat from activities in space, including the proliferation of large satellite constellations.
The Operational Land Imager (OLI) on NASA / USGS’s Landsat 8 satellite captured a stunning image of Italy’s Mount Vesuvius peeking through a sea of clouds. Upon closer inspection, we can clearly see the ridge surrounding the cone, a remnant of the collapsed caldera of an older volcano, Mount Somma, from which the cone of Vesuvius emerged.
NASA / ESA’s Hubble Space Telescope captures a jellyfish-like dying star located 5,000 light-years from Earth in nebula NGC 2002. When stars like our Sun grow old, they eventually expand and glow red, effectively turning into a red giant, which then begins to cast off their outer layers of material into space.
NASA / ESA’s Hubble Space Telescope captured this peculiar image of M110, a dwarf elliptical galaxy located 2.674 million light-years from Earth in the constellation, and a dwarf elliptical galaxy that is a satellite of Andromeda in the Local Group.
Unlike NASA’s Curiosity, the agency will equip future Mars rovers with their revolutionary shape memory alloy (SMA) spring tires, which can return to their original shape after being bent, stretched, heated, and cooled.
