While this "mass loss" may not sound very large, in fact it is an enormous rate among stars of all types. A very faint structure, seen in argon, is evidence of an interaction between winds from Eta Car A and those of Eta Car B, the hotter, less massive, secondary star.
Eta Car A is one of the most massive and most visible stars in the sky. Such massive stars also have a short lifetime, and we expect that Eta Carinae will explode within a million years. Eta Carinae was first catalogued by Edmund Halley in In Eta Carinae was one of the brightest stars in the sky.
It then slowly faded until, in , it became invisible in the sky. Detecting Other Worlds. Transiting Exoplanet. Direct Imaging. Exoplanet Diversity. Orbital Distance. Forms of Light. Seeing Through Smoke. Electromagnetic Spectrum.

What is the bright white star in the sky? It's the star Sirius in the constellation Canis Major, brightest star in the sky.
The bright planet Venus is also up before dawn now. But you'll know Sirius, because Orion's Belt always points to it.
Stacey Kaleev Teacher. Is Sirius the North Star? The brightest star in the sky — Sirius in the constellation Canis Major, the Greater Dog — will someday serve as a very reasonable, and certainly very noticeable, South Star. Our current North Star , Polaris, comes closer than that to the north celestial pole.
Arcelia Langpeter Teacher. What is the North Star called? Answer: The Earth spins on its "axis". We call that star the " North Star " since it sits in the direction that the spin axis from the northern hemisphere of Earth points.
At present, the star known as Polaris is the North Star. Lacrimioara Carilla Reviewer. What is the brightest planet?
Not all of these objects are stars though. Venus , which can be seen with the unaided eye from Earth, is the brightest planet in our Solar System. Venus was given the nickname evening star and morning star because of its bright, consistent presence.
