If not perfect, then this spiral galaxy is at least one of the most photogenic. An island universe containing billions of stars and situated about 40 million light-years away toward the constellation of the Dolphinfish (Dorado), NGC 1566 presents a gorgeous face-on view. Classified as a grand design spiral, NGC 1566 shows two prominent and […]

Will our Sun look like this one day? The Helix Nebula is one of brightest and closest examples of a planetary nebula, a gas cloud created at the end of the life of a Sun-like star. The outer gasses of the star expelled into space appear from our vantage point as if we are looking […]

Transformed into the petals of a flower, 16 exposures show the passage of day into night in this creative timelapse skyscape. Start at the top and move counterclockwise to follow consecutive moments as the twilight sky turns an ever darker blue and night blossoms. Each exposure was recorded on the evening of April 22, calculated […]

Shackleton crater lies at the lunar south pole. Peaks along the 21 kilometer diameter are in sunlight, but Shackleton’s floor is in dark permanent shadow. Still, this image of the shadowed rim wall and floor of Shackleton crater was captured from NASA’s ShadowCam, an instrument on board the Korea Pathfinder Lunar Orbiter (KPLO) launched in […]

Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth’s Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is the large galaxy rendered in blue hues in this infrared image […]

Galaxies are fascinating. In galaxies, gravity alone holds together massive collections of stars, dust, interstellar gas, stellar remnants and dark matter. Pictured is NGC 5128, better known as Centaurus A. Cen A is the fifth brightest galaxy on the sky and is located at a distance of about 12 million light years from Earth. The […]
