- NASA's Nancy Grace Roman Telescope is set to explore dark matter and potential alien worlds
NASA's Nancy Grace Roman Telescope is set to launch in late August, aiming to study dark matter, dark energy, and discover exoplanets. The telescope was completed early and under budget, marking a significant advancement in astrophysics.
- After exoplanets, the hunt for 'exomoons' begins
Scientists have discovered a potential exomoon orbiting a brown dwarf within the system of the star CD-35 2722. This marks the beginning of the hunt for exomoons following advancements in exoplanet research.
- Shape-shifting mirrors on NASA’s new space telescope could unveil Jupiters like our own
NASA’s Nancy Grace Roman Space Telescope, launching soon, will use an active coronagraph to block starlight and capture images of exoplanets similar to those in our solar system. It features a 300-megapixel camera for wide-field imaging and aims to study dark matter, dark energy, and detect thousands of new exoplanets.
- We’ve found a rocky, temperate planet’s atmosphere for the first time
Astronomers have discovered an atmosphere around a rocky, temperate exoplanet for the first time. Previously, atmospheres were only detected on very large or extremely hot exoplanets, but this discovery involves a planet potentially suitable for life.
- Astronomers find biggest super-puff planets yet that are lighter than cotton candy
Astronomers discovered two super-puff planets that are less dense than cotton candy, orbiting a star 1,110 light-years away. These are the largest exoplanets found with such low density.
- 'We were astonished': Millions of exoplanets could be born near active supermassive black holes
The article suggests that millions of exoplanets may form near active supermassive black holes, a discovery that surprised researchers due to the extreme environments typically associated with such regions.
- Most exoplanets might be 'soot factories,' scientists say: 'Like you have a natural diesel engine'
Scientists suggest most exoplanets may act as 'soot factories,' emitting soot similar to a natural diesel engine, as depicted in an illustration showing black circles releasing soot.
- 'Hot Jupiter' winds blasting at over 15,000 mph reveal 1st evidence of exoplanets with magnetic fields
A 'Hot Jupiter' exoplanet's winds exceed 15,000 mph, providing the first evidence of magnetic fields in exoplanets. An illustration depicts the magnetic activity observed.
- How do you study an invisible exoplanet? Astronomers discover planetary 'fingerprints' in the rings around stars
Astronomers have discovered a method to study invisible exoplanets by analyzing planetary 'fingerprints' in the rings surrounding stars. The PDS 70 system is highlighted as an example of this observational technique.
- NASA’s Roman telescope could reveal 100,000 hidden worlds
NASA’s Roman Space Telescope could discover around 100,000 exoplanets, surpassing all previous missions combined. It will explore unexplored regions of the Milky Way, identify Earth-sized planets, analyze alien atmospheres, and provide insights into planetary formation.
- The most common type of planet in the galaxy may not look anything like Earth on the inside
The most common type of planet in the galaxy may have internal structures vastly different from Earth, potentially featuring white-hot molten cores. This finding challenges assumptions about planetary composition and highlights diversity in exoplanet characteristics.
- Powerful AI finds 100+ hidden planets in NASA data including rare and extreme worlds
Astronomers used the AI tool RAVEN to analyze NASA's TESS mission data, confirming over 100 exoplanets, including 31 new ones. The discoveries include rare planets with extreme characteristics, such as those orbiting stars in under a day and those in the 'Neptunian desert.'
