True
Sirius is the brightest star in the sky. It is in the constellation of Canis Major, visible in the northern hemisphere during the winter months. Canis Major is also known as the Big Dog, earning the star its nickname -- "the Dog Star."
Assuming the observer is in the North, then the southern hemisphere would be tilted towards the sun during the Winter Solstice in December. However, for observers in the Southern Hemisphere, the Winter Solstice would occur in June, and the northern hemisphere would be tilted towards the sun.
In that case, it is basically summer in the northern hemisphere, and winter in the southern hemisphere.In that case, it is basically summer in the northern hemisphere, and winter in the southern hemisphere.In that case, it is basically summer in the northern hemisphere, and winter in the southern hemisphere.In that case, it is basically summer in the northern hemisphere, and winter in the southern hemisphere.
In the northern hemisphere's summer solstice, around the 21st of June, the northern hemisphere is tilted towards the sun. In the southern hemisphere's summer solstice, around the 21st of December, the southern hemisphere is tilted towards the sun.
If you are in the northern hemisphere, they are visible in all seasons.
During Spring evenings (April)
As seen from Earth, Sirius is the brightest sky in the night sky. It is best on view during the months of winter in the northern hemisphere. It can be found by finding the constellation of Orion, and using Orion's Belt, to follow down low and to Orion's left.
Best viewing period is in the Northern Hemisphere is during the winter months.
There are no constellations in the northern hemisphere, but several of them are visibleto observers located there.Depending where you are in the northern hemisphere, you can see anywhere betweenhalf of all the visible stars (from the north pole) to all of the visible stars (from the equator).At any location on earth, Aries is visible during some part of the year.
Lyra contains the third brightest star in the northern hemisphere, Vega. From spring to autumn, it is clearly visible, while during the winter months, it is visible low on the northern horizon.
If you know where Canis Major is, then you cannot miss Sirius. It is not only the brightest star in Canis Major, but the brightest in the night sky. Find Orion in the south, during the winter months in the northern hemisphere. Then find Orion's Belt, and follow its line of stars down to the left and you will find Sirius. It is unmistakeable. It is now April, but it is still visible in the early part of the night, but by next month it will be harder to see and won't be easily visible again until next winter.
Both but mainly the Northern. Visible at latitudes between +90° and −40° Best visible at 21:00 (9 p.m.) during the month of August
In December it is winter in the northern hemisphere
Orion is behind the sun in the summer sky - which is why you can't see it. Orion is visible during winter nights, in the Northern Hemisphere.
In the southern hemisphere it is winter when in the northern hemisphere it is summer.
If you live in the northern hemisphere, Cygnus the Swan is best visible during the late fall, winter and early spring almost directly overhead.
