In the case of V838 Monocerotis, the light echo produced was unprecedented and is well documented in images taken by the Hubble Space Telescope. While the photos appear to depict an expanding spherical shell of debris, they are actually formed by the illumination of an ever-expanding ellipsoid with the progenitor star at one focus and the ...
The unusual spiral morphology of BX442 was discovered using images obtained from the Hubble Space Telescope by a team of astronomers led by David R. Law of the University of Toronto. While the Hubble image suggested the galaxy's spiral structure however, it didn't conclusively prove that the galaxy rotated like modern-day spiral galaxies.
The nebula's temperature is measured at 1 K (−272.15 °C; −457.87 °F) making it the coolest natural place currently known in the Universe. [ 4 ] [ 5 ] [ 6 ] The Boomerang Nebula is believed to be a star system evolving toward the planetary nebula phase.
Least massive galaxy Segue 2 ~550,000 M Sun: This is not considered a star cluster, as it is held together by the gravitational effects of dark matter rather than just the mutual attraction of the constituent stars, gas and black holes. [141] [142] Most massive galaxy ESO 146-5 ~30×10 12 M Sun: Central galaxy in Abell 3827, 1.4 Gly distant ...
The apex of the Sun's way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The general direction of the Sun's Galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 60 sky degrees to the direction of the Galactic Center. The Sun's orbit about the Milky Way is ...
The pillars shown in the image are 5 light-years tall, which means that the distance from one end to the other is roughly 300,000 times as far away as Earth is from the sun.
In this zoomed-in detail of the Hubble image of Abell 370, the host galaxy where the 44 stars were discovered appears several times: in a normal image (left), and a distorted image appearing as a ...
SMACS J0723.3–7327, commonly referred to as SMACS 0723, is a galaxy cluster about 4 billion light years from Earth, [2] within the southern constellation of Volans (RA/Dec = 110.8375, −73.4391667).
