The NASA / ESA Hubble Space Telescope captured an incredible image of Abell 1351, a massive galaxy cluster that lies in the constellation Ursa Major in the northern hemisphere. It was photographed using its Wide Field Camera 3 and Advanced Camera for Surveys.
We see streaks of light that are actually the images of distant galaxies and the result of gravitational lensing. The latter is essentially an astrophysical phenomenon that occurs when a massive celestial body such as a galaxy cluster distorts spacetime sufficiently strongly to affect the path of light passing through it. Now here’s what a black hole sounds like at the center of the Perseus Galaxy Cluster.

Celestron – NexStar 127SLT Computerized Telescope – Compact and Portable – Maksutov-Cassegrain Optical Design – SkyAlign Technology – Computerized Hand Control – 127mm Aperture
- Computerized star locating telescope: The Celestron NexStar 127SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it.
- Compact and portable: This telescope for adults and kids to be used together is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere.Optical Tube:Aluminum
- Maksutov-cassegrain optical design: The NexStar 127SLT is the second-largest in the SLT family. The 127mm aperture gathers enough light to see our Solar System and beyond. View Saturn’s rings, Jupiter’s cloud bands, and the Moon in brilliant detail.
- Fast setup with skyalign: Celestron’s proprietary SkyAlign procedure has you ready to observe in minutes. Simply center any 3 bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects.
- Bonus free starry night software: The NexStar 127SLT Computerized Telescope includes a free download of one of the top consumer rated astronomy software programs for an interactive sky simulation.
These Snapshot Programs are lists of separate, relatively short exposures which can fit into gaps between longer Hubble observations. Having a large pool of Snapshot candidates to dip into allows Hubble to use every second of observing time possible and to maximise the scientific output of the observatory,” said the European Space Agency.
