Nasa launches Nancy Grace Roman telescope to explore dark energy and exoplanets

Nasa has launched the Nancy Grace Roman telescope from Florida, beginning a mission to investigate dark energy, black holes, and exoplanets.

  • The Nancy Grace Roman telescope has a field of vision at least 100 times larger than the Hubble Space Telescope.
  • The telescope is expected to discover tens of thousands, possibly up to 100,000, new exoplanets.
  • Its primary lifespan is five years, with a goal to operate for 10 years.

Nasa's next-generation Nancy Grace Roman telescope successfully launched into space from Florida on Sunday morning. The mission aims to explore dark energy, black holes, and other mysteries of the Universe.

The telescope will capture vast panoramic views of space, with a field of vision significantly larger than the Hubble Space Telescope. It is embarking on a 100-day journey to a vantage point approximately one million miles from Earth.

Once in position, the telescope will begin charting exoplanets and conducting sweeping surveys to investigate dark energy and dark matter. Nasa administrator Nicky Fox stated that Roman is expected to discover tens of thousands, potentially up to 100,000, new exoplanets.

The telescope is named after physicist Nancy Grace Roman, Nasa's first chief astronomer and first female executive. Its primary lifespan is five years, with an operational goal of 10 years.

Why this matters: The mission is expected to revolutionise understanding of the Universe, including dark energy and dark matter, which are believed to constitute about 95% of the Universe.
