"Deploying both wings of the telescope while part of the fully assembled observatory is another significant milestone showing Webb will deploy properly in space. Performed in early March, this test involved commanding the spacecraft's internal systems to fully extend and latch Webb's iconic 6.5 meter (21 feet 4-inch) primary mirror. In order to perform the groundbreaking science expected of Webb, its primary mirror needs to be so large that it cannot fit inside any rocket available in its fully extended form. In a recent test, NASA's James Webb Space Telescope fully deployed its primary mirror into the same configuration it will have when in space. NASA's James Webb Space Telescope Full Mirror Deployment a Success Its capabilities will enable the observatory to answer questions about our own solar system and investigate faint signals from the first galaxies formed 13.5 billion years ago. The Webb telescope will look at every phase of cosmic history, including the first glows after the Big Bang that created our universe and the formation of the galaxies, stars and planets that fill it today. Webb will act as an infrared sleuth, detecting light that is invisible to us and revealing otherwise hidden regions of space. In addition to investigating the wealth of planets outside of our solar system, the observatory will peer back to some of the earliest galaxies that formed after the Big Bang and the very structure of the universe itself. The telescope is expected to launch Saturday morning from French Guiana and live coverage will be available on NASA’s website beginning at 6 a.m. The James Webb Space Telescope will be the premier space observatory of the next decade when it launches Saturday. We can play around with our models of boson stars and see how well they can explain the orbital dynamics of this system and use that information to glimpse into the dark corners of the universe.We’re about to have eyes on the invisible side of space. Secondly, if it is a boson star, this system is the perfect experimental setup. Most importantly, this unique system gives us a rare opportunity to study the behavior of strong gravity, allowing us to examine Einstein's theory of general relativity to see if it holds up. While it's unlikely that this is actually the discovery of a boson star, the authors still urged follow-up observations. The researchers pointed out that a simple model of boson dark matter could produce enough boson stars to make this result in the Gaia data plausible, and that replacing a putative black hole with a boson star could explain all of the observational data. Because dark matter doesn't interact with other particles or with light, we could detect them only through the gravitational influence on their surroundings - like if a regular star were to orbit a boson star. What's the biggest black hole in the universe?īoson stars would be entirely invisible. Black holes may be swallowing invisible matter that slows the movement of stars 1st image of our galaxy's 'black hole heart' unveiled The smallest clumps of bosonic dark matter could be as small as stars, and these hypothetical objects get a new name: boson stars. Some of these clumps could be the size of entire star systems, but some could be much smaller. Most importantly, they would have the ability to form large clumps. These kinds of bosons wouldn't carry forces, but they would still soak the universe. While we know of only a limited set of bosons in the Standard Model of particle physics, there's nothing, in principle, stopping the universe from having many more kinds. Bosons are the particles that carry the forces of nature for example, a photon is a boson that carries the electromagnetic force. One of these models hypothesizes that dark matter is a new kind of boson. Most theoretical models assume that dark matter is smoothly distributed in each galaxy, but there are models that allow it to clump up on itself. We still do not have a solid understanding of its identity. Dark matter is an invisible form of matter that makes up the vast majority of the mass of every single galaxy.
