Backyard telescope captures The Eyes in Markarian's Chain

Astrophotographer Ronald Brecher captured a striking image of Markarian's Chain—an extended string of galaxies in the Virgo Galaxy Cluster—from his home in Guelph, Canada, using a Skywatcher Esprit 120 and multiple filters to accumulate about 9.5 hours of exposure. The shot highlights the galaxy pair NGC 4438/NGC 4435, nicknamed 'The Eyes', with nearby ellipticals M86 and M84 also visible; Markarian's Chain is a dense segment of the roughly 2,000-member Virgo Cluster. Brecher captured the image between April 17 and 27, and the article explains how to spot Markarian's Chain in spring skies: find Leo's Denebola and Virgo's Vindemiatrix and sweep a 6-inch telescope to the patch between them.

"NASA's Hubble Captures Galaxies Under Ram Pressure in Virgo Cluster"

Nasa's Hubble Space Telescope captures a stunning image of LEDA 42160, a galaxy in the Virgo cluster, 52 million light-years away, undergoing ram pressure stripping, which can both hinder and enhance star formation. The image shows bright patches indicating active star-forming areas, providing valuable data for studying the effects of ram pressure on dwarf galaxies within large clusters like Virgo.

"Starless Wonders: Unveiling the Enigma of Ultra-Compact Galaxies"

Observations show that interactions with more massive galaxies can strip dwarf galaxies of their stars, leaving behind only their dense central star clusters. This process has been observed in the Virgo galaxy cluster, where dwarf galaxies have been transformed into ultra-compact dwarf galaxies. These findings shed light on the profound effects of cluster environments on the stellar structure and evolution of galaxies.
