Chandra Detects Giant X-Ray Bubble Around Young Sun-Like Star HD 61005
NASA astronomers using the Chandra X-ray Observatory have discovered a vast, million-degree gas bubble surrounding HD 61005, a 100-million-year-old Sun-like star about 120 light-years away. Its stellar wind is far stronger than today’s solar wind, forming a 200 astronomical unit-wide astrosphere that offers rare insight into how the young Sun once shaped the early solar system.
