SN H0pe Discovery-A Sneak Peek of the Universe's Expansion Rate The astonishing discovery of supernova SN H0pe, a supernova far away from us, whose image has been manipulated in space by gravity, has given astronomers an opportunity to begin solving some important mysteries about the rate at which the universe is expanding. Gravitational lensing, when a mass like a galaxy curves light from a more distant object and magnifies it, has been used to observe a Type Ia supernova, labeled SN H0pe. Type Ia supernovae are key cosmic markers since they always appear with consistent brightness, hence, serving as dependable tools in measuring astronomical distances. The James Webb Space Telescope played a vital role in this discovery. Combining the power of gravitational lensing and time-delay observations, astronomers were able to make a more precise measurement of the Hubble constant ever obtained.

Congratulations to the 2024 Nobel Prize winners in Physics! 🎉 This year’s two Nobel Laureates in Physics have used tools from physics to develop methods that are the foundation of today’s powerful machine learning. John Hopfield created an associative memory that can store and reconstruct images and other types of patterns in data. Geoffrey Hinton invented a method that can autonomously find properties in data, and so perform tasks such as identifying specific elements in pictures. Their discoveries push the boundaries of science, inspiring future generations of physicists and innovators.🏆🥇 Their work not only deepens our comprehension of fundamental physical laws but also impacts technology and society in profound ways. We honor their dedication, curiosity, and contributions that shape the future of science and humanity! #NobelPrize #Inventors #WorldWide #SOPA #RUSL

Do you know about the Pulsar? A pulsar is a rapidly spinning neutron star, which is the small incredibly dense remnant of much more massive star. A teaspoon of matter from a neutron star weights as much as Mount Everest and the neutron star is so compact that a ball about fifteen miles across contains more matter than our sun. Neutron stars spin between seven and forty thousand times a minute and form with incredibly strong magnetic field. Rapid spin and intense magnetic fields drive powerful beams of electromagnetic radiation including gamma rays. As the pulsar rotates, these beams sweep the sky like a lighthouse. To a distant observer, the pulsar appears to blink on and off. Pulsars slow down as they age but some of the oldest pulsars spin hundreds of times a second. Each of these millisecond pulsars orbits a normal star. Over time, the impact of gas pulled from the normal star has spun the pulsar up to incredible speeds. This accretion may be the cause of their weaker magnetic fields. Despite this, these pulsars also emit gamma rays. By:Sayani Kariyawasam #pulsar #neutronstar #SOPA #RUSL #FAS

Do you know about the Great Red Spot on Jupiter? The Great Red Spot is a huge storm on Jupiter. It's so big that Earth could fit inside it! This storm has been going on for more than 400 years. The winds are very strong, moving at 432 kilometers per hour (268 miles per hour). The storm looks red, but scientists aren’t sure why. It might be because of sunlight hitting chemicals in Jupiter's air.The Great Red Spot is shrinking over time. It used to be three times the size of Earth, but now it’s a little bigger than our planet. Even though it’s getting smaller, the storm is still strong and powerful.

Kardashev Scale : Measure of civilization energy use The Kardashev Scale, introduced by Soviet astronomer Nikolai Kardashev in 1964, it provides a way to evaluate a civilization’s technological advancement by measuring its ability to harness and convert energy. • Type I: This type can fully use and store all of the energy available on its planet, including solar power, geothermal energy, wind, and other natural resources. A Type I civilization would require approximately 10^16 to 10^17 watts. Earth’s current energy consumption places us below this level, at around Type 0.7, as we still rely heavily on fossil fuels and have not maximized our use of renewable resources. • Type II: A civilization that can harness the total energy output of its star. This would involve capturing the energy emitted by the star, possibly through the construction of a Dyson Sphere, a theoretical megastructure that could surround a star and collect a significant portion of its energy. A Type II civilization would control around 10^26 watts. • Type III: At this stage, a civilization would be capable of managing the energy resources of an entire galaxy, drawing power from billions of stars. Such an achievement would suggest mastery over interstellar travel and energy transmission on a galactic scale. The energy usage at this level would reach approximately 10^36 watts. Extensions of the scale include: • Type IV: Controls the energy of an entire universe. • Type V: Hypothetically, taps into multiple universes. By : Pubudu Dehigolla #sopa #sopaweeklypost #sopafacts

Are We Alone In The Galaxy? The question "Are We Alone In The Galaxy?" has intrigued people for a long time. A new study from the University of Nottingham suggests there could be 36 intelligent civilizations capable of communication in our galaxy. This estimate is based on the idea that life evolves similarly on other planets as it does on Earth, taking about 5 billion years. Previous methods, like the Drake equation, offered a wide range of possibilities, but this new study refines the estimate using updated data. However, finding these civilizations is challenging, as they may be thousands of light years away. By : Kalaani Anuththara #sopa #sopaweeklypost #sopafacts

New observations from the James Webb Space Telescope suggest that Uranus' moon Ariel may have a liquid underground ocean. Ariel, one of 27 moons around Uranus, has intrigued scientists due to its potential for water, alongside other moons like Umbriel, Titania, and Oberon. Ariel's surface features canyons, grooves, and smooth regions, and carbon dioxide ice was detected, especially on the side facing away from its orbit.
