The Jupiter-size object is about seven times larger than the white dwarf. It circles this stellar cinder every 34 hours, more than 60 times faster than Mercury orbits our Sun.
First Possible ‘Survivor' Planet Hugging a White Dwarf Star
Surveying sunspots is the most basic of ways we study how solar activity rises and falls over time, and it’s the basis of how we track the solar cycle.
How Scientists Around the World Track the Solar Cycle
Experts from NASA and NOAA discuss their analysis and predictions for the new solar cycle.
Solar Cycle 25 Is Here, Scientists Explain What That Means
Venus is proving to be an exciting place of discovery, though it had not been a significant part of the search for life because of its extreme temperatures, atmospheric composition and other factors.
