article_snippet.sent: Welcome to the exoplanet HD 189733b, where temperatures reach 3,000°C (5,400°F) and winds are in excess of 620mph (1,000km/h).
article_snippet.sent: And wind speeds are in excess of 620 miles per hour.
article_snippet.sent: 620mph (1,000km/h) Conditions:
article_snippet.sent: Glass particles in the atmosphere give it it dazzling blue colour.
article_snippet.sent: Coupled with the extremely high wind speed of 620 mph (1,000km/h), it reveals the planet has an extremely turbulent atmosphere - and is almost certainly inhospitable to life.
article_snippet.sent: To measure the wind, the team measured how the sodium lines were the teamblueshifted’ - meaning its light was stretched in such a way to indicate its light was coming towards us.
