Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, a project that involved some of the most well-known astronomers of the day, including Edwin Hubble.
NASA's Hubble Space Telescope has photographed the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990.
Visible as a small, sparkling hook in the dark sky, the beautiful object below snapped by NASA's Hubble Space Telescope is known as J082354.96+280621.6, or J082354.96 for short.
NASA's Hubble Space Telescope has broken its own record in the quest to find the furthest supernova of the type used to measure cosmic distances.
Messier 77 is a galaxy in the constellation of Cetus, located approximately 45 million light-years away from Earth.
The bright galaxy pictured below, known as IRAS 23436+5257, was captured by the NASA/ESA Hubble Space Telescope.
Galaxies have been known to take numerous forms. Indeed, elliptical blobs, swirling spiral arms, bulges, and disks are all known components of the wide range of galaxies astronomers have observed using telescopes like NASA's Hubble Space Telescope.
A team of astronomers using NASA's Hubble Space Telescope has taken an important step closer to finding the "birth certificate" of an ancient star.
It may look like something from "The Lord of the Rings," trilogy (think the Eye of Sauron), but this fiery swirl is actually a real-life planetary nebula known as ESO 456-67 imaged by NASA's Hubble space telescope.
NASA's Hubble space telescope has captured an image of HH 151, a bright jet of glowing material trailed by an intricate, orange-hued plume of gas and dust.
NASA's space telescope has captured a rather impressive image of a thin, glittering streak of stars known as the spiral galaxy ESO 121-6, which lies in the southern constellation of Pictor (The Painter's Easel).
An odd star that flashes like a strobe light may actually be a pair of young stars just a few thousand years old, says a team using the Spitzer and Hubble space telescopes.
The further away scientists look, the further back in time they see. Astronomers use this method to study the evolution of the Universe by analyzing nearby and more distant galaxies and comparing their features.
Globular clusters are approximate spherical collections of old stars, with around 150 of them scattered around our Milky Way galaxy.
A rather busy patch of space was recently snapped by NASA's Hubble Space Telescope. Scattered with many nearby stars, the field boasts numerous galaxies in the background.
The constellation of Ursa Major (The Great Bear) is home to Messier 101, which astronomers have dubbed the Pinwheel Galaxy.
Astronomers using NASA's Spitzer and Hubble space telescopes have managed to probe the stormy atmosphere of a brown dwarf, creating the most detailed "weather map" yet for this class of cool, star-like orbs.
Mingus - or more formally, SN SCP-0401 - is a Type Ia supernova with a redshift of 1.71, dating back 10 billion years. It's exceptional for its detailed spectrum and precision color measurement, unprecedented in a supernova so distant, says the team.
The vast disk of debris encircling Fomalhaut B hosts a rogue planet which may unleash a cataclysm in 2032.
The Universe often fools our eyes, offering the false impression that celestial objects are located at the same distance from Earth.
