What are the two new zodiac signs?

Excuse me, could you please elaborate on the topic of the two new zodiac signs? I'm intrigued to learn more about this recent addition to the traditional 12 zodiac signs. Are these new signs based on astronomical discoveries or are they a product of cultural or spiritual evolution? How do they fit into the existing astrological framework, and what impact do they have on the interpretation of horoscopes and astrological predictions? I'm eager to understand the significance and implications of these new signs in the world of astrology.
