Astronomers develop software to help eliminate streaks marring Hubble Space Telescope images caused by rapidly increasing numbers of Earth-orbiting satellites.
Despite the huge distance to its target, the Webb telescope has managed to “see” a vast plume of water vapour jetting from geysers on Saturn’s moon Enceladus.
New images of two galaxies, a star cluster and the famed “Pillars of Creation” showcase the value of multi-wavelength astronomy when it comes to seeing the Big Picture.
Some tightly-packed globular clusters show signs of unseen black holes affecting the movements of their stars. Astronomers are using the Hubble Space Telescope to look for evidence of such hidden monsters.
Galaxy clusters serve as gravitational zoom lenses for the Hubble Space Telescope, magnifying the light from more remote background galaxies to shed light on the nature of such lenses and the distribution of dark matter.
