Why Can’t We See Planets If We Can See Distant Galaxies? We are able to see high-definition images of galaxies that are thousands of light-years away, but not the planets of those far away galaxies. This is because far-off galaxies are astronomically larger and brighter than...

It is the type star of the “Cepheid” variables which are used as “standard candles” to calculate the distances to globular clusters and nearby galaxies. There is a direct relationship between the absolute magnitude of Cepheids and their period, so if you measure the period, you can ...
Anyone with access to a DSLR camera and a tripod (or a steady surface) can take stunning photos of the night sky with all its glorious stars. You will even start to see some Nebulae, Galaxies, Globular Clusters,the Milky Way, Meteorites, Auroras, and more. ...
But the Milky Way isjust one of bilions ofgalaxies that we know about! Some other scientists say there are 2,000,000,000,000,000,000 stars!Largest star in the galaxyThe largest star that we know about is called the Pistol Star(手枪星). The Pistol Star iscloser to the center of the...
and are great for viewing objects like craters on the moon. Telescopes are bulkier but provide a more detailed view, which are best for seeing planets like Jupiter and Saturn, and fainter objects like nebulae and even galaxies. Even if you don’t have one of your own, a number ofHipcamps...
Dwarf galaxies (矮星系) may have as few as ten million stars, and giant galaxies (巨星系) mayhave one trillion stars.Therefore, according to the ESA astronomers, there could be asmany as 1,000,000,000,000,000,000,000,000 stars in the universe. However,this is just a very rough ...
We asked amateur astronomer and astrophotographer Giuseppe Donatiello a few questions on how to photograph the Tiangong space station. Giuseppe Donatiello Giuseppe Donatiello is an Italian amateur astronomer, astrophotographer and author who is known for his discovery of six nearby dwarfgalaxiesand seve...
It's even believed by some that the universe itself may be a fractal and as you zoomed in you would discover it's made up of billions of galaxies. 有些人甚至认为宇宙本身可能是一个分形,当你放大时,你会发现它由数十亿个星系组成。
