For the small outer irregular moons of Uranus, such as Sycorax, which were not discovered by the Voyager 2 flyby, even different NASA web pages, such as the National Space Science Data Center [6] and JPL Solar System Dynamics, [5] give somewhat contradictory size and albedo estimates depending on which research paper is being cited.
A size comparison of the six largest galaxies of the Local Group, including the Milky Way. The Milky Way is one of the two largest galaxies in the Local Group (the other being the Andromeda Galaxy), although the size for its galactic disc and how much it defines the isophotal diameter is not well understood.

<p>You might think of our Solar System as a pretty special place — and considering it's produced the only known example of life, that's probably a fair point of view — but the Milky Way, our ...
In 2018, the Gaia project of the European Space Agency, designed primarily to investigate the origin, evolution and structure of the Milky Way, delivered the largest and most precise census of positions, velocities and other stellar properties of more than a billion stars, which showed that Sgr dSph had caused perturbations in a set of stars ...
Gaia is a space observatory of the European Space Agency (ESA) that was launched in 2013 and is planned to operate until March 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [5] [6] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.

Artists' impression of Giotto, the European Space Agency's first interplanetary mission, launched in July 1985. ARD, launched October 1998 – Demonstration mission to test new technologies in atmospheric entry design. CoRoT, launched December 2006 – CNES-led space telescope mission to search for rocky exoplanets and perform asteroseismology ...
The galaxy group that includes the Milky Way. Bullet Group: Named in comparison with the Bullet Cluster, being of similar formation, except smaller. Also has a systematic catalogue name SL2S J08544-0121. As of 2014, it was the lowest mass object that showed separation between the concentrations of dark matter and baryonic matter in the object ...
By way of comparison, Hubble orbits 550 km (340 mi) above Earth's surface, and the Moon is roughly 400,000 km (250,000 mi) from Earth. Objects near this Sun–Earth L 2 point can orbit the Sun in synchrony with the Earth, allowing the telescope to remain at a roughly constant distance [ 29 ] with continuous orientation of its sunshield and ...
