In colorful photographs of galaxies, stars, planets, and more, what you see isn’t necessarily what you get 在星系、恒星、行星等色彩斑斓的照片中,你所看到的并不一定就是你所得到的 作者:Phil Plait; …
The first images include four galaxies, chosen because they represent the different types of galaxy that the survey will find. There is a barred spiral galaxy, like our Milky Way, and a similar galaxy undergoing vigorous star formation. There is also a galaxy that seems to haverecently merged,...
“The WFSS mode on NIRISS allows Webb to obtain spectra but for thousands of objects, such as galaxies, at the same time over the detector’s entire field of view (4.84 arcmin2). The spectra of thousands of galaxies will enable measurement of their distances, ages, and ...
Not all quartz formations are listed here, and this article does not cover the types of different crystals. Check out the article onvarious types of quartz crystalsfor a list of quartz types, to see if the one you are looking for, has had an in-depth article written about it. Note:Some...
In Ref. [27], the authors extensively investigated the shadow of this charged black hole with scalar hair from the perspectives of four different types of observers. Guo et al. also examined the quasinormal modes (QNMs) of this four-dimensional charged black hole with scalar hair, and their...
This lining up of galaxies can be helpful for astronomers performing certain types of research though. “Chance galactic alignments such as this provide astronomers with the opportunity to delve into the distribution of dust in these galaxies,” Hubble scientistswrite. “Galactic dust – the dark te...
of galaxies,” Giardino notes, a process by which we might also help trace the history of our universe since the first galaxies began to form. And while Webb can’t actually show us an active black hole, this image allows scientists to study the com...
Astrophysicists have long tried to simulate the formation of our spiral galaxy, the Milky Way. Until now, such attempts have faltered on one of two points: Either the simulated spiral galaxies displayed too many stars at the center or the overall stellar mass was several times too big. For...
In this paper, we investigate the shadows and rings of the charged Horndeski black hole illuminated by accretion flow that is both geometrically and optically thin. We consider two types of accretion models: spherical and thin-disk accretion flow. We find that in both types of models, the si...
galaxies, the Chandra data revealed a shockwave caused by two of the galaxies colliding into each other at 2 million miles per hour. This shockwave is heating up gas to tens of millions of degrees. In the Carina Nebula image, the X-rays shown in purple pick out some of the hottest and...
