4. D 推理判断题.根据最后一段"Michelle Ntampaka, an astronomy expert, expects to see lots more astronomers using artificial intelligence techniques to analyse their data in the future. That's because newer telescopes don't collect images of stars and galaxies (星系) so much as digital data ...
An artist’s impression of a star’s dusty debris disk, thought to be produced when asteroids or other planetesimals collide and fragment. Astronomers studying the debris disk around the star HD 206893 have imaged a wide gap in the disk extending from about 50 to 185 au from the star. Afte...
But several thousand other exoplanets are known to astronomers whose habitability is misleading as there is no evidence about contrasting effects take place between these bright stars and their suspected exoplanets. Since majority of the exoplanets are found using transit principle method, so in this ...
A hot planet transits in front of its parent star in this artist impression of an exoplanet system. Credit: ESA/ATG medialab, CC BY-SA 3.0 IGO The nature of planets orbiting stars in other systems will be the focus for ESA's fourth medium-class science mission, to be launched in mid ...
‘missing mass’ in the orbital velocities of galaxies in clusters and stars at the edges of galaxies. Dark matter is inferred to exist from itsgravitational effectson visible matter and background radiation, but it emits no visible light and does not interact with any other matter except by ...
Most people do not think of spectroscopy when someone mentions astronomy. However, astronomical observations allow us to investigate and understand the chemistry of diverse objects, such as exoplanets, dense molecules clouds and even other galaxies, while we cannot travel to them. ...
galaxies forming, to watching how stars are born from swirling dust and gas. With itsfirst year of science operations planned out, we’re just scraping the surface of what this new tool could be used for. We’ll have to wait and see what other astronomical marvels it will be able to ...
Last December, for instance, Kepler found a planet 2.4 times larger than Earth orbiting in its star's habitable zone— that just-right range of distances where liquid water, and perhaps life as we know it, can exist. The Kepler team and other research groups have detected several other worl...
This decade has seen an explosion of research into exoplanets -- planets orbiting stars other than our sun. Now, the European Space Agency (ESA) is beginning its own exoplanet mission with the launch of the Characterizing Exoplanet Satellite, aka Cheops,
Spitzer views the universe in theinfrared lightthat is a bit less energetic than the light our eyes can see. Infrared light can easily pass through stray cosmic gas and dust, allowing researchers to peer into dustystellar nurseries, the centers of galaxies, and newly formingplanetary systems. ...
