A car on a road following very closely behind an open bed truck with a couple of dozen large pine tree trunks stacked up at an angle, looking like they are just aching to slide off and kill people who are in a car following very closely behind.

I've seen enough horror movies to know this is a really bad idea

Direct imaging and astrometric detection of a gas giant planet orbiting an accelerating star Direct imaging of gas giant exoplanets provides information on their atmospheres and the architectures of planetary systems. However, few planets have been detected in blind surveys with direct imagin...

There are similar findings from direct imaging: e.g. the discovery paper for HIP 99770 b (29 Cyg b), a similar recent system, & a recent demographics study

Astronomers used NASA’s James Webb Space Telescope to directly image 29 Cygni b, which weighs 15 times Jupiter. They found evidence for heavy chemical elements like carbon and oxygen, which strongly suggests it formed like a planet by accretion within a protoplanetary disk, and not like a star through fragmentation.

Webb’s NIRCam (Near-Infrared Camera) was used in its coronagraphic mode, in which a wedge (indicated by the blue box) is used to block the light of the host star (labeled A and marked with a star symbol) to reveal the planet. This image combines light from three filters between 4 and 5 microns. The planet is brightest in the blue filter, then green, then red, so it appears as an off-white dot in the color composite. If carbon dioxide weren’t present, the planet would appear noticeably redder.

In this image, the color blue is assigned to 4.1 micron light, green to 4.3 micron light, and red to 4.6 micron light.

🔭🪐 my team took this image of 29 Cygni b, a super giant planet 130 light years from us, with JWST. we found some interesting clues that suggest that this planet (~15x the mass of Jupiter) accreted more than 100 times the mass of the Earth in carbon- and oxygen-rich material during its formation

Discovery of a Low-Mass Companion to the Accelerating Star HIP 53005 with Strongly Conflicting Mass Estimates We present the discovery of a low-mass companion located at $ρ$ $\sim$ 0\farcs{}85 ($r_{\rm proj} \approx 62~au$) from the early-type 1.2 Gyr-old star HIP 53005 using direct imaging data from the Suba...

Accelerating star surveys with SCExAO strike again! This time a work led by Uyama-san identifying a potential GJ229B-like companion (or something else strange going on)

A telescopic image of a flat, inclined fuzzy disc with bright rings and dark gaps, all concentric. There is a small blob in one of those gaps. An inset that zooms in on the centre of the disc shows a second blob in another gap.

A new solar system in the making?

For the second time ever, two planets have been directly observed forming around a host star. Our VLT and VLTI have helped astronomers confirm the presence of a second gas giant orbiting the star WISPIT 2.

Pro tip: when writing a proposal, write an introduction that, you know,*introduces* the topic to a reviewer who might not be thinking of your specialty every waking hour of their day.

A good introduction, that also shows that you know what others are doing on the problem, really helps a proposal.

Steward teams are building instruments for Lazuli — a new space telescope launching by 2029 as part of the Eric & Wendy Schmidt Observatory System. Our adaptive optics will image giant exoplanets nearly a billion times dimmer than their host stars! bit.ly/4dkXYH1

Here come the cold giants! A combination of RV and astrometry reveals several "Jupiter analogues", among them one planet (around HIP 39330, a G5V star, ca. 100 ly away) that matches Jupiter quite nicely: a=5.05 au, e=0.078, M=1.67 M_jup. If only we could quickly check for terrestrial planets inside!
