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!

Why did Homo sapiens outlast all other human species?

  From - Live Science By  Mindy Weisberger Edited by - Amal Udawatta Reproductions of skulls from a Neanderthal (left), Homo sapiens (middle) and Australopithecus afarensis (right)   (Image credit: WHPics, Paul Campbell, and Attie Gerber via Getty Images; collage by Marilyn Perkins) Modern humans ( Homo sapiens ) are the sole surviving representatives of the  human family tree , but we're the last sentence in an evolutionary story that began approximately 6 million years ago and spawned at least 18 species known collectively as hominins.  There were at least nine  Homo  species — including  H. sapiens  —  distributed around Africa, Europe and Asia by about 300,000 years ago, according to the Smithsonian's  National Museum of Nat ural History  in Washington, D.C. One by one, all except  H. sapiens  disappeared.  Neanderthals  and a  Homo  group known as the  Denisovans  lived alongside...

New Zealand loses first naval ship to sea since WW2

  Aleks Phillips   BBC New  ,   Michael Bristow,    BBC World Service Edited by - Amal Udawatta US Navy HMNZS Manawanui capsized after running aground off the coast of Samoa The Royal New Zealand Navy has lost its first ship to the sea since World War Two, after one of its vessels ran aground off the coast of Samoa. HMNZS Manawanui, a specialist diving and ocean imaging ship, came into trouble about one nautical mile from the island of Upolu on Saturday night local time, while conducting a survey of a reef. It later caught fire before capsizing. All 75 people on board were evacuated onto lifeboats and rescued early on Sunday, New Zealand's Defence Force said in a statement. Officials said the cause of the grounding was unknown and will be investigated. Reuters All 75 people on board have now safely been rescued The incident occurred during a bout of rough and windy weather. Military officials said rescuers "battled" currents and winds that pushed ...

From a Trump presidency to 'game-changing' lawsuits: Seven big climate and nature moments coming in 2025

      From -BBC World News   By-  Jocelyn Timperley and Isabelle Gerretsen   Edited by - Amal Udawatta Getty Images Some key events coming up in 2025 have game-changing potential for our planet. Here, two of the BBC's environment journalists analyse what they could mean for the climate and nature. As countries unveil new climate targets, Donald Trump enters the White House for a second term and a potentially game-changing ruling for future climate lawsuits unfolds – 2025 is set to be a big year for climate and nature.  Speaking in his  New Year's message  in late December, secretary-general of the United Nations  António Guterres said that the world is witnessing "climate breakdown – in real time".  "We must exit this road to ruin. In 2025, countries must put the world on a safer path by dramatically slashing emissions and supporting the transition to a renewable future," he said, stressing that "it is essential – and it is possible...
