The Webb Space Telescope makes the pillars of creation with new depth and clarity

October 20, 2022 mohmad free

One of the most famous and impressive images in modern astronomy, which reveals huge constellations of interstellar gas and dust called the Pillars of Creation, has been rendered with greater depth, clarity and color by the James Webb Space Telescope. The new view of the plumes, when captured in 1995 by Webb’s former observatory, the Hubble Space Telescope, was revealed by NASA on Wednesday, three months after revealing Webb’s inaugural set of cosmic images as it began full operations. The charming images show huge, towering plumes of dense clouds of…

Astronomers discover ‘cry from a young star’ that could help better understand star formation

August 31, 2022 mohmad free

The researchers discovered a dipole gas stream flowing from Y256, a “young star” in the Small Magellanic Cloud. The speed of this stream is more than 54,000 kilometers per hour. The Small Magellanic Cloud is a dwarf galaxy about 200,000 light-years away from the Milky Way. The mechanism of star formation is greatly influenced by the presence of heavy elements in interstellar matter. But the abundance of heavy elements was lower in the early universe than in the present universe because there was not enough time for nucleosynthesis to produce…

An unusually large and compact triple star system has been discovered for the first time

July 24, 2022 mohmad free

Earlier this year, scientists at the Niels Bohr Institute at the University of Copenhagen announced the discovery of an unusual trio of stars. The system they discovered consists of two stars orbiting each other and a third, more massive star orbiting the pair. The The research was published in the Monthly Notices of the Royal Astronomical Society in June. “To our knowledge, it is the first of its kind ever to be discovered. We know of many triple star systems (three star systems), but they are usually significantly less massive,”…

Scientists have warned that supermassive black holes will collide with each other and distort space and time

February 26, 2022 mohmad free

A new study has found that two supermassive black holes will merge within 10,000 years, in a collision that will send ripples across the universe. The research, led by a team of astronomers from the California Institute of Technology, found that two supermassive black holes, about 9 billion light-years away in deep space, orbit each other every two years. Each supermassive black hole has a mass hundreds of millions of times greater than the mass of our Sun. Furthermore, the two objects are relatively close to a distance of 1,950…

Astronomers discover the planet where it rains gems and mineral clouds

February 23, 2022 mohmad free

Usually rainy days are very miserable but that is not the case in a faraway planet where it can make you rich. Experts believe that a huge exoplanet located 855 light-years away rains on liquid sapphires and sapphires. WASP-121 b, as the planet is known, is home to clouds of vaporized metals rather than the thinner stuff we get back here on Earth. Clouds on the planet consist mainly of metals such as iron, magnesium, chromium, and vanadium. “This rain will be different from any known rain in the solar…

The sun is erupting nonstop this month and ‘giant torches are incoming’

February 19, 2022 mohmad free

The sun has been very busy the past few weeks. On Tuesday, our star unleashed two massive explosions from its far side in what was already an intense month of solar activity. A remarkable coronal mass ejection (CME) was recorded by NASA’s STEREO-A spacecraft in the early hours of February 15. Large-scale eruptions are giant volcanic eruptions that send plasma rushing through space — and the sun has undergone many of them over the course of the month. If they hit Earth, plumes of material could create geomagnetic storms that…

The James Webb Space Telescope reaches its orbital destination one million miles from Earth

January 25, 2022

Today, at about 12:30 a.m., the James Webb Space Telescope fired its thrusts for 297 seconds and completed its last post-launch trajectory correction. This burn helped bring the world’s most powerful space telescope into its final orbit – L2, or the second Lagrangian point between the Sun and Earth. The telescope will orbit the sun and will be 1 million miles or 1.5 million kilometers from Earth. “Webb, welcome home!” NASA Administrator Bill Nelson said in a statement. We are one step closer to unlocking the secrets of the universe.…

The largest and most powerful space telescope has successfully deployed its golden mirrors and testing of individual mirror clips is now complete. Our mirror pane deployments are complete! 🎉 Using the actuators, each section was moved to approximately half the length of the paperclip to clear the mirrors from the release restrictions and to give each section sufficient space to align the mirror. https://t.co/XWbVLQuch1 #UnfoldTheUniverse pic.twitter.com/d121DHldiX – NASA’s Web Telescope (NASAWebb) Jan 19 2022 Erin Wolfe, Webb’s program manager at Ball Aerospace, explained how the mirrors were transported and tested.…

Newly discovered exoplanet host stars will soon be consumed: study

January 17, 2022

A new study said that three giant planets orbit dangerously close to their stars and will be devoured by their stars. She added that the host stars are nearing the end of their lives. NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has spotted these exoplanets, called TOI-2337b, TOI-4329b and TOI-2669b, which have short orbits around giant stars. We are pleased to report that three of the most important Jupiters ever found orbit advanced stars NASA_TESS And Tweet embed today! Each of these planets has a special place, and together they…

Astronomers have found evidence of a second supermoon outside our solar system

January 14, 2022

For only the second time, astronomers have discovered what appears to be a moon orbiting a planet in another solar system. Just like the first time, this moon has features that indicate that such moons can be very different from those inhabiting our solar system. Data obtained by NASA’s Kepler Space Telescope before it retired in 2018 indicated a moon 2.6 times the diameter of Earth orbiting a Jupiter-sized gas giant about 5,700 light-years from our solar system in the direction of Cygnus and Lyra. Scientists said on Thursday. New…
