Galaxy Cluster Abell NGC2218, located 2 billion light-years away in the Draco constellation. It is a massive cluster with as many as 10,000 individual galaxies. The light from many of these galaxies undergoes gravitational lensing. (Andrew Fruchter et al., WFPC2, HST, NASA)
Light wave captured at 10 trillion frames per second taken by TheSlowMoGuys.
Galaxy cluster, Abell S1063, located 4.5 billion light-years away. The characteristic signs of gravitational lensing can also be seen in this Hubble Space Telescope photo. (NASA, ESA, and M. Montes, University of New South Wales, Sydney, Australia)
The Tulip Nebula, also known as SH2-101, located 8,000 light years away in the constellation Cygnus. It is an emission nebula which means it emits its own light due to ionization from nearby young stars.

Some newborn stars eject powerful jets of ionized radiation, illuminating the surrounding gas clouds. These rare formations are known as herbig–haro objects. (ESA/Hubble & NASA, B. Nisini)
Image of the Cat’s Paw Nebula taken by the James Webb Space Telescope. It features concentric shells of gas and dust expanding outwards from a central, dying star. (NASA, ESA, CSA, STScI)
Photo of protoplanetary disk HH 30 in the Taurus Molecular Cloud taken by the James Webb Space Telescope. It contains a young star which emits a luminous jet of outflowing gas. (NASA/ESA/CSA)
NGC 5394 and NGC 5395, an interacting pair of galaxies in the Canes Venatici constellation. Their merger will be known collectively as the Heron Galaxy. (International Gemini Observatory/NOIRLab/NSF/AURA)
NGC 1333, a star-forming region located 1,000 light years from Earth and home to many energetic proto-stars less than a million years old. (T.A. Rector/University of Alaska Anchorage, H. Schweiker/WIYN and NOIRLab/NSF/AURA)
A star cluster known as G35.2-0.7N, a region of intense star formation. It is home to a massive B-type star that produces a protostellar jet. It is the source of the dust clouds which fill the center this image. (ESA/Hubble & NASA, R. Fedriani, J. Tan)
Wide-angle view of the Large Magellanic Cloud, one of the Milky Way’s satellite galaxies. (CTIO/NOIRLab/NSF/AURA/SMASH/D. Nidever, Travis Rector, Mahdi Zamani & Davide de Martin)
Spiral Galaxy IC 342 located roughly 11 million light-years from Earth. (NOIRLab/NSF/AURA/T.A. Rector (NSF NOIRLab/University of Alaska Anchorage) & H. Schweiker)
Photo depicting gravitational lensing around galaxy cluster CL0024+1654, located around 5 billion light years from Earth. The multiple blue loops scattered across the image are actually copies of the same distant spiral galaxy. (NASA, W.N. Colley and E. Turner, J.A. Tyson)
Nearby spiral galaxy, Messier 106. The supermassive black hole at its center produces two extra spiral arms, shown in green, composed of hot gas. (ESA/Webb, NASA & CSA, J. Glenn)
The Double Helix Nebula, located only 300 light-years from the supermassive black hole at the center of the Milky Way. Incredibly strong and twisted magnetic fields in this region of the galaxy give the nebula its unique geometry. (NASA/JPL-Caltech/M. Morris, UCLA)
Dwarf planet Eris situated near Pluto in the Kuiper Belt. Discovered in 2005, its atmosphere freezes into snow when it is farther from the Sun and thaws when it gets closer. Eris is slightly smaller than Pluto, but more massive. (Southwest Research Institute)
An interacting pair of galaxies known as IC 1623. As the galaxies merge, intense star formation is triggered which is accompanied by bright outbursts of radiation. (X-ray: NASA/CXC/SAO; IR: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare and J. Major)
Photo of Pluto’s surface taken by the New Horizons spacecraft in 2015. Evidence can be seen for a cryovolcano, a type of volcano that spews out icy water, methane, or ammonia instead of molten rock. (NASA / Johns Hopkins University Applied Physics Laboratory / Southwest Research Institute)
The Red Spider Nebula viewed through the James Webb Space Telescope. It was produced by a star like our Sun reaching the end of its life and shedding its outer layers into space. Radiation from the star’s exposed core continues to ionize clouds of outflowing gas. (NASA/ESA/CSA)
Galaxy group VV 166, located 300 million light years away. The arms of the spiral galaxy at the top, NGC 70, are distorted due to tidal interactions with neighboring galaxies. (International Gemini Observatory/AURA)
