project
NASA mission launched in 2018 that monitors stellar brightness dips; source of the candidate that became GJ 523b and of more than 8,000 candidates overall.
No evidence-backed relationships are recorded.
Warwick-led astronomers tie niobium at over 1,000 times solar levels in a white dwarf to a candidate planet made from what the star shed as it died. If it holds up, it shows planets can still form after a star has died.
Reality
Southampton's Black Hole Hunters project wants volunteers to vet AI-screened telescope data for black holes beyond the roughly 70 whose locations are known. A volunteer's flag picks a target for telescope follow-up, and the team counts a discovery only once it detects gravitational self-lensing.
Reality
Planets inherit their direction of travel from the disk that formed them. A planet running backward around a small cool star is therefore a formation problem, and one team's answer is a second disk, tilted from the first.
Reality
A University of Tokyo group found the planet in brightness data already in hand, where the secondary eclipse arrived earlier than a circular orbit allows. Its star's surface is 8,400 C and the orbit takes two days.
Reality
A Wisconsin group reports a planet that is mostly rock where theory expects a gas envelope. Its own authors say astronomers cannot finish the composition argument alone.
