The featured image shows a Falon 9 rocket transiting in front of the Sun in mid May. The heat from the rocket's exhaust makes the Sun's outline appear to ripple. Please see the explanation for more detailed information.

Explanation: The launch of a rocket at sunrise can result in unusual but intriguing images that feature both the rocket and the Sun. Such was the case last month when a SpaceX Falcon 9 rocket blasted off from NASA’s Kennedy Space Center carrying 53 more Starlink satellites into low Earth orbit. In the featured launch picture, the rocket’s exhaust plume glows beyond its projection onto the distant Sun, the rocket itself appears oddly jagged, and the Sun’s lower edge shows peculiar drip-like ripples. The physical cause of all of these effects is pockets of relatively hot or rarefied air deflecting sunlight less strongly than pockets relatively cool or compressed air: refraction. Unaware of the Earthly show, active sunspot region 3014 — on the upper left — slowly crosses the Sun.

Je spreekt nu met Tracy: Hoi! Welkom bij de chat van DHL Parcel. Ik ben Tracy de chatbot. 🙂 Ontvang je een pakket via ons? Of heb je iets verstuurd?

Jij: Ontvanger

Tracy: Dan ben je bij mij aan het goede adres! 😉 Wat kan ik voor je doen?

Jij: melding zegt afgeleverd maar heb niets ontvangen

Tracy: Ik begrijp dat je pakje wel de status “bezorgd” heeft, maar dat het pakket toch niet bezorgd is. Heb ik dat goed begrepen?

Jij: Ja, dat klopt

Tracy: In deze drukke periode zien we vaak dat het pakket een werkdag later alsnog wordt geleverd. Is de melding dat het pakket is bezorgd al meer dan een werkdag geleden gegeven?

Jij: Nee

Tracy: Dan raad ik je aan een werkdag af te wachten. Heb je het pakket een werkdag later nog steeds niet? Dan zoeken we het graag verder voor je uit.

Jij: gekkenhuis
