Phobos photobombs Hubble’s picture of Mars!
Hubble’s 13 exposures happened to capture a timelapse of one of Mars’ two tiny moons.
Hubble saw Phobos. The other moon is Deimos.
Both are only a few miles wide!
Astronomer Asaph Hall discovered them in 1877 with a telescope in Washington, D.C.
Many spacecraft have looked at the Martian system.
1969, Mariner 7
1971, Mariner 9
1977, Viking 1
1997, Pathfinder
2000, Mars Global Surveyor
2005, Spirit
2008, Mars Reconnaissance Orbiter
2013, Curiosity
Phobos and Deimos are the Greek personifications of fear and terror.
Does this Phobos photobomb strike fear into your heart?
