Regulus Regulus is 0.46 degree from the ecliptic, the closest of the bright stars, and is regularly occulted by the Moon. Occultations by the planets Mercury and Venus are possible but rare, as are occultations by asteroids. The last occultation of Regulus by a planet was on July 7, 1959, by Venus.

- A fundamental property of main sequence stars like our. Sun is their stability over long periods of time. • In the case of the Sun, the geological record indicates. that it has been emitting energy at its present rate for. several billion years, with relatively small variation. • The key to this stability is that main sequence stars. are in a state of near perfect hydrostatic equilibrium. • In hydrostatic equilibrium the pressuregradients pro-. duced by thermonuclear fusion and internal heat al-. most exactly balance the gravitational forces. Thus the starting point for an understanding of stellar. structure is an understanding of hydrostatic equilibrium. and departures from that equilibrium.

- One class of stars can induce this effect. They’re known as carbon stars. A fine example of just such an object rides high in the late spring sky for northern hemisphere observers. This is the variable star Y Canum Venaticorum, also abbreviated as Y CVn or “ La Superba ” (The magnificent).This name was given to the star by Father Angelo Secchi in the mid-19 th century.’ve shown off carbon stars such as La Superba and Hind’s Crimson Star at public star parties to great effect. They can be an excellent star party “ secret weapon ” when every other ‘scope down the line is aimed at the Orion nebula. For a faint constellation, Canes Venatici has lots to offer.

- The pole star is 55 degrees above the horizon. Remember your latitude is equal to the altitude (angle above the horizon) of Polaris. Any star with a declination of 35 degrees will just skim the horizon at this latitude.

Capricornus Constellation It lies in the fourth quadrant of the southern hemisphere (SQ4) and can be seen at latitudes between +60° and -90°. The neighboring constellations are Aquarius, Aquila, Microscopium, Piscis Austrinus, and Sagittarius. Capricornus has three stars with known planets and also contains a Messier object, M30 (NGC 7099).The brightest star in the constellation is Deneb Algedi, Delta Capricorni.ven though Capricornus is the second faintest constellation in the sky, after Cancer, it is associated with myths and images that go way back to the 21st century BC. The story of Capricornus originated with the Babyonians and Sumerians.

Star brightness versus star luminosity Surface temperature. Also, if a star has the same radius as the sun but a higher surface temperature, the hotter star exceeds the sun in luminosity. The sun’s surface temperature is somewhere around 5800 Kelvin (9980 o Fahrenheit).That’s 5800 degrees above absolute zero, the coldest temperature possible anywhere in the universe.et’s presume a star has the same surface temperature as the sun, but sports a larger radius. In that scenario, the star with the larger radius claims the greater luminosity. In the example below, we’ll say the star’s radius is 4 solar (4 times the sun’s radius) but has the same surface temperature as our sun.

Stratocumulus cloud Stratocumulus Perlucidus is a layer of stratocumulus clouds with small spaces, appearing in irregular pattern, through which clear sky or higher clouds can be seen. Stratocumulus Translucidus consist of separate groups of stratocumulus clouds, with a clear sky (or higher clouds) visible between them. No precipitation in most cases. Pattern-based varieties. Stratocumulus Undulatus clouds appear as nearly parallel waves, rolls or separate elongated clouds, without significant vertical development.

Coordinates There are a couple of popular ways of specifying the location of a celestial object. The first is what you would probably use to point out a star to your friend: the altitude-azimuth system. The altitude of a star is how many degrees above the horizon it is (anywhere from 0 to 90 degrees). The azimuth of a star is how many degrees along the horizon it is and corresponds to the compass direction. Azimuth starts from exactly North = 0 degrees azimuth and increases clockwise: exactly East = 90 degrees, exactly South = 180 degrees, exactly West = 270 degrees, and exactly North = 360 degrees = 0 degrees.

The Deep Photographic Guide to the Constellations Cassiopeia is as big W in the sky a well known and easy to find constellation . In mid of November it culminates at about 21:00 local time (9:00 pm). With its very northern declination of +46 to +87 degrees it is circumpolar for most northern hemisphere observers. I.e. it never sinks below the horizon and can be seen all the year. Cassiopeia is positioned directly in the Milky Way.

Luminosity If we work in solar units indicated with a symbol, we can ignore the constants and simply write L = R2T4. For example, if a star has the same surface temperature as the sun and a radius that is twice as big, its luminosity must be L = (2 R)2(T)4 = 4L.One can experiment with the relationships between luminosity, temperature (spectral type), and radius with the Stellar Luminosity Calculator.f we work in solar units indicated with a symbol, we can ignore the constants and simply write L = R2T4.

- The letters across the bottom represent the spectral class of stars, or color of stars. The temperature of the stars measured across the bottom of the scale are measured in Kelvin. Zero Kelvin equals -273 degrees Celsius, -459 degrees Fahrenheit. As you can see, there are only a few categories of stars. Most stars in our universe are main sequence stars, including our sun Sol. Notice how the biggest stars are the brightest but not the hottest. The white dwarf stars are near the end of their life and losing much of their brightness but they are very hot.

Scorpius The Sumerians also identified the constellation with the scorpion, or Gir-tab. Scorpius is depicted with its tail and sting poised in the air, ready to strike. The constellation Scorpius occupies an area of 497 square degrees and contains ten stars with known planets. It can be seen at latitudes between +40° and -90° and is best visible at 9 p.m. during the month of July. Astronomically, the Sun lingers in Scorpius only for a week, from November 23 to November 30, but most astrologers consider it to be in the sign of Scorpio from October 23 to November 23. In sidereal astrology, the Sun passes through Scorpio from November 16 to December 16.

- During the day, the temperature at and near the equator is a comfortable +20 to +27 Celsius and at night on the same spot, it's below -70 Celsius. Mars is also the only other planet with a proper day-night cycle, at least what us Earth-bound would call proper. Vesta: -188C to -3C. The highest temperature on Vesta was recorded at -3 Celsius.

Cumulus cloud Cumulus clouds are a genus of free-convective low-level cloud along with the related limited-convective cloud stratocumulus. These clouds form from ground level to 2,000 metres (6,600 ft) at all latitudes. Stratus clouds are also low-level.

Red Dwarfs: The Most Common and Longest-Lived Stars The sun, by comparison, can reach up to 27 million F (15 million C) . The low temperatures of red dwarfs means they are far, far dimmer than stars like the sun. Their low temperature also means that they burn through their supply of hydrogen less rapidly. While other, more massive stars only burn through the hydrogen at their core before coming to the end of their lifetimes, red dwarfs consume all of their hydrogen, in and out of their core. This stretches the lifetime of red dwarfs out to trillions of years, far beyond the 10-billion-year lifetime of sun-like stars.
