Astronomical Phenomena

Images depicting cosmic events and celestial bodies, including asteroids and nebulae, with vibrant colors showcasing the universe's mystery and beauty.

Early on April 21, 2002, a large (X-1) flare and a partial halo coronal mass ejection (CME) exploded out from the Sun from near its west (right) limb. A pronounced proton storm of high-energy particles took place at about the same time as seen in the LASCO (Large Angle and Spectrometric Coronagraph) C3 image taken in visible light from the Solar and Heliospheric Observatory (SOHO). The accompanying coronal mass ejection can also be seen in the image.

Stein_Sun Visualization of the complex magnetic field produced as magnetic flux rises toward the Sun¹s surface from the deep convection zone. The image shows a snapshot of how the magnetic field has evolved two days from the time uniform, untwisted, horizontal magnetic field started to be advected by inflows at the bottom (20 megameters deep). Axes are in megameters, and the color scale shows the log of the magnetic field strength.This transmission electron microscope image shows SARS-CoV-2 also known as 2019-nCoV, the virus that causes COVID-19. Virus particles emerge from the surface of a cell cultured in the laboratory. Spikes on the outer edge of virus particles give coronaviruses their name, shaped like a crown. Image captured and colorized at Rocky Mountain Laboratories in Hamilton, Montana.

These exposures were taken that day, when the comet was at a distance of about 2.9 AU from the sun.Polished slab of Brazilian Agate.Like great friends, galaxies stick together. Astronomers using NASA's Spitzer Space Telescope have spotted a handful of great galactic pals bonding back when the universe was a mere 4.6 billion years old.Thermal image of mother cradling six month baby boyThis series of images obtained by NASA's Cassini spacecraft shows several views of the north polar cloud covering Saturn's moon Titan.This image is a blinking of two 14-minute exposures of NASA's Dawn spacecraft from 600,000 miles from Earth.

The eagerly awaited results announced last year from the orbiting Wilkinson Microwave Anisotropy Probe resolve several long-standing disagreements in cosmology rooted in less precise data. Specifically, present analyses of above WMAP all-sky image indicate that the universe is 13.7 billion years old (accurate to 1 percept), composed of 73 percept dark energy, 23 percept cold dark matter, and only 4 percept atoms, is currently expanding at the rate of 71 km/sec/Mpc (accurate to 5 percept), underwent episodes of rapid expansion called inflation, and will expand forever. Astronomers will likely research the foundations and implications of these results for years to come.
