Hubble telescope's observations exploring the evolution of local spiral galaxies

From - Gemes Webb Space Telescope,

Edited by - Amal Udawatta,

Here we have some brand new images of the Phantom Galaxy, M74 taken by a tag team of Hubble and Webb. Left is an image at optical wavelengths from Hubble Space Telescope , with the right hand image being James Webb Space Telescope 's infrared view of the same galaxy. In the centre is the astonishing composite of the two. The image is part of Webb's picture of the month series. 

Hubble's image of M74 comes from a set of observations exploring the evolution of local spiral galaxies such as M74 with the aim of gaining insights into the history of star formation in these spirals. Webb gazed into M74 with its Mid-InfraRed Instrument (MIRI) revealing delicate filaments of gas and dust in M74's grandiose spiral arms. M74 is a particular class of spiral galaxy known as a ‘grand design spiral’, meaning that its spiral arms are prominent and well-defined, unlike the patchy and ragged structure seen in some spiral galaxies. Webb's images will enable astronomers to learn more about the earliest phases of star formation in the local Universe.

Hubble’s sharp vision at ultraviolet and visible wavelengths complements Webb’s unparalleled sensitivity at infrared wavelengths, as do observations from ground-based radio telescopes such as ALMA Observatory . By combining data from telescopes operating across the electromagnetic spectrum, scientists can gain greater insight into astronomical objects than by using a single observatory — even one as powerful as Webb!

Who Was the Real Marilyn Monroe?

From - Smithsonian Magazine, By - Grant Wong Historian, University of South Carolina, Edited by - Vinuri Randhula Silva, “Blonde,” a heavily fictionalized film by Andrew Dominik, explores the star’s life and legend in a narrative that’s equal parts glamorous and disturbing Marilyn Monroe’s final interview is a heartbreaker. Published in Life magazine on August 3, 1962—just a day before the actress died of a barbiturate overdose at age 36—it found Monroe reflecting on her celebrity status, alternatively thoughtful, frank and witty. “When you’re famous you kind of run into human nature in a raw kind of way,” she observed. “It stirs up envy, fame does. People you run into feel that, well, who is she—who is she, who does she think she is, Marilyn Monroe?” That same question—who was the real Monroe?—has sparked debate among cinema scholars , cultural critics , historians , novelists , filmmakers and th...

New Comet SWAN Now Visible in Small Scopes

From :- Sky & Telescope By :- Bob King Edited by :- Amal Udawatta This spectacular image of Comet SWAN (C/2025 F2) was taken on April 6th and shows a bright, condensed coma 5′ across and dual ion tails. The longer one extends for 2° in PA 298° and the other 30′ in PA 303°. Details: 11"/ 2.2 RASA and QHY600 camera. Michael Jaeger Amateur astronomers have done it again — discovered a comet. Not by looking through a telescope but through close study of publicly released, low-resolution images taken by the Solar Wind Anisotropies (SWAN) camera on the orbiting Solar and Heliospheric Observatory (SOHO). On March 29th, Vladimir Bezugly of Ukraine was the first to report a moving object in SWAN photos taken the week prior. Michael Mattiazzo of Victoria, Australia, independently found "a pretty obvious comet" the same day using the same images, noting that the object was about 11th magnitude and appeared to be brightening.

Geckos shed around every month in adulthood

From -Earth Unreal, Edited -by Vinuri Randula Silva, All geckos shed their skin at fairly regular intervals, with different species differing in timing and method. When shedding begins, geckos accelerate the process by detaching the loose skin from their body and eating it. Geckos shed around every month in adulthood, and will often eat their shed skin. This is to gain back some of the nutrients they lose by shedding, and also to avoid being detected by predators in the wild.
